| Warning to everyone, Magellan has just switched over to TELE ATLAS maps and no longer with NAVTEQ as of October 2010. I bought a second 3045 LM unit: the first 3045 unit had NAVTEQ (bought 1 month ago) and the second unit bought 2 days ago had TELE ATLAS. I ran the 2 units side by side and there was a huge difference in routing. The TELE ATLAS unit had terrible routing: it would take me on some insane routes that made no sense and were often circuitous and long. The NAVTEQ unit on the other hand had perfect routing. In addition, there was no true re-routing on the TELE ATLAS unit: it would try to force me to take a U-turn. The NAVTEQ unit would re-route perfectly. To sum up, I would avoid buying any new Magellan units as they now use TELE ATLAS maps and the routing is terrible compared to the previous Magellan NAVTEQ units. You should call customer service to confirm that Magellan is now using Tele Atlas and complain, as anyone who bought LIFETIME maps will be affected. I had just converted over from Garmin and was very happy with the Magellan NAVTEQ unit, but the newest Magellan units all have TELE ATLAS and have terribly inept routing. |

Interesting although it would be helpful if you clarify how you saw that they had switched? Looking at the copyright ? What are the map revision numbers ? The Spring update was version 39.
Let's also clarify something from the get-go that the problems you are seeing (although it would help to have specific examples of the Navteq/TeleAtlas differences before full judgment can be passer) are not due to the TeleAtlas maps in themselves as evidenced by the excellent routes provided by TomTom GPS systems (some have argued recently that they are better than the routes provided by Garmin systems using Navteq maps) but rather, one has to assume, to the way Magellan have implemented them, which is a problem of course but not the same problem.
So since you have both systems, can you provide some actual route examples ? |

there is a new update beyond 39 which is not yet listed on the magellan website. i bought a new unit 3045-LM from best buy 2 days ago and saw that it had map update 41. the first 3045 unit i bought back 1 month ago in September had map 39. after i got crazy routing with the map 41, i called magellan cust service and they told me that the new map update 41 is Tele Atlas and that the new units shipping out had just been changed to Tele Atlas. As mentioned, you may want to confirm yourself with customer service. Apparently customer service said they were already getting complaints with the new Tele Atlas maps. I am hesitant to post the routes as it is to and from my place of work (if you PM me, i can give you the routes). But it scares me to think that if i continue using this in places i am not familiar with, I won't even know that I am being taken on terrible routes. I decided to return the unit.
continued : i also have a garmin 350 that i ran side by side with the magellan 3045 navteq and the magellan 3045 tele atlas, and the garmin 350 (also navteq) had the exact same routes as the magellan 3045 navteq. i was extremely happy with the first magellan 3045 navteq unit that i bought in september, and in fact like it better than any garmin unit i have had, as it gives so much better early turn warnings and more detail at complicated highway intersections or exits (i was very frustrated with the garmin 350/660 as i used to miss many turns with the garmin due to late warnings and poor detail at highway intersections/branches/exits). so far i feel that the magellan navteq unit is the best gps i have had, but given my experience with the magellan tele atlas unit, i don't plan to buy any more magellan units. i plan to keep the original magellan 3045 navteq unit (and return the magellan 3045 tele atlas) and though i have lifetime map updates, i don't plan to update if magellan keeps on using teleatlas, for fear of getting bad routes. |

several things:
1. i have kept the original 3045 navteq map 39 unit. however, i updated the firware from 1.41 to 3.11. and after i updated to firware 3.11, i started having terrible traffic reception. after i complained to customer service, they told me it was a known issue, and that they switched traffic providers (from navteq to clear channel). obviously, all these changes from magellan has made both of my units worse (clear channel traffic, tele atlas maps)
2. with regards to my 2nd 3045 unit with map 41/teleatlas: i asked magellan to send me an older 3045-LM unit with map 39 and firmware 1.41. they promised to do so, but when i received it, it had map 41/teleatlas and firware 3.11. Annoying... i tried the unit out, and sure enough, the routing was abominable. and the re-routing still tried to force me on u-turns rather than calculating a better route. i will be sending this replacement unit back to magellan and switching over to garmin until magellan gets their act together.
3. magellan customer service did tell me that they were getting a lot of complaints about the new teleatlas units.
i posted my same review above on amazon (under the 5045 unit) on october 26th and gave the unit a 1 star review. what was truly mind boggling is that there were only 27 reviews over a period of 5 months from june until my review in october 26th. after i posted the one star review to warn people of the problems, all of a sudden over a span of 3 days, the number of reviews doubled: 25 more reviews over a span of 3 days were posted, mostly 5 and 4 stars praising how great the magellan 5045 is (and many of the 5 star reviewers had never written a review before). now i don't want to sound like a consipirist, but i find it strange that 25 reviews (mostly 5 and 4 star) appear in 3 days when previously it took 5 months for 27 reviews to be posted. hmmmmmm...could these be bogus reviews by magellan aimed to bury my review? my 1 star review/warning was in effect buried under 25 more reviews.... |

| Seems odd indeed, but stranger things have happened! Anyway your feedback is safe here though and I posted a news item on the front page yesterday : http://www.gpspassion.com/ . We really need to find a way to test some of these problem routes you are seeing, I'll pull out my 1440 to see if I can find a way to simulate a route. |

great thanks for posting this news. i feel it's important for everyone to know. and i encourage anyone who does have or plans to purchase the new magellan teleatlas units to run them side by side with the older magellan navteq units (map 39, firmware 1.41). pay particular attention to the difference in routing, re-routing, and traffic reception. i agree with you that we need to finda a way to test the problem routes (as mentioned, if you would like to PM me, i can send you the routes). thanks.
when i told customer service that the teleatlas units tended to try to u-turn when re-routing, their suggested solution was to "turn off u-turns", which is a solution i find unacceptable. some of the reviews on amazon (5045 units) have echoed similar experience in poor routing, re-routing/u-turning, and traffic reception.
here's a comment from another 1 star review on the new magellan 5045 unit (Oct 29, "steve"):
"The GPS sent us in circles. I called Magellan and they told me some models had a software glitch. They tod me not to reorder this model until they worked out the problem. Amazon refunded all my money. These GPS cause too many problems. I'll go to map quest when need and print out diretions. Map quest has only gotten me lost 1 time in about 10 years."
another comment re: poor traffic reception (amazon 11/2/10, R. Thomas):
- The traffic Receiver never worked and when it did it would last about 5 minutes.
amazon review (3065 unit, Anna Hope 10/18/10, 2 stars):
"The Fastest Route option is inaccurate to say the least. During my morning commute the gps fails (post firmware update) to pick up traffic data - this is critical with a 86 mile commute 3 days a week. While on route experience has taught me the route to use, during the initial period I tried some of the routes provided by the GPS unit and found them shorter but not quicker. Once the GPS unit reroutes to the route I am using the ETA drops by minutes, bottom line the quickest route does not work. This option also has a tendency to want to take me through residential neighborhoods (even with the use highways option enabled) instead of highway routes, which might be slightly faster if there were no traffic lights or school buses. Magellan needs to do some serious adjustments to its algorithms.
We will persevere in hopes that Magellan can update its firmware and
I will update the review accordingly, currently though it is hard to recommend the unit in this state. "
another amazon review (3055 unit)
2.0 out of 5 stars Poor navigation logic, October 31, 2010
By David E. Meyer "Dave" (Atlanta, GA) - See all my reviews
(REAL NAME)
This review is from: Magellan RoadMate 3055 4.7-Inch Widescreen Bluetooth Portable GPS Navigator with Lifetime Traffic (Electronics)
"I tested this unit against Google Maps and the Tomtom XL340TM on ten locations for fastest time. The worst performance was from an Atlanta, GA suburb to Tallahassee, FL. The Roadmate had the distance at 399 miles, while the other two had it at 295 & 300 miles. The Roadmate also projected an average speed of over 75 mph for the trip. There were other disappointing navigation choices but this was the worst.
On another trip I took it rutted me off a state Hwy and through a subdivision then back to the state Hwy. It latter routed me off a paved road and on to a gravel road just to save 2/10 of a mile."
Regarding poor re-routing (forcing u-turns)
Amazon review for 3055, October 21, 2010, By reg (Houston)
"I am a novice at using a GPS and am not real up-to-date on using many electronics. I have a fear of getting lost, so a GPS should be a good item for me. The first time I used this one, I was going home from my vet's office. I knew where I was going, but wanted to know where it would take me. It didn't go the way I preferred. It kept wanting me to u-turn to get back to its preferred route. Eventually, it gave up and recalculated another route I would not choose. It did get me to a street I had been meaning to try out, so it was nice to find where that one would go to get me home. I still don't use that route."
Amazon 5045 review: October 30, 2010 By Values Privacy "vdch"
"okay. but odd routing, and no mac support"
"The Bad
It wants to route me through the streets with the most stop signs for some reason? It's as good as how well it routes. That is its primary purpose and it does a mediocre job."

FYI: here is an amazon customer posting a reply to my review and sharing the same complaints:
Posted on Nov. 7, 2010 7:26 PM PST
JamCracker says:
I have this unit and now wonder I wish I'd have seen your review earlier - now I see it's TeleAtlas. I can't understand the re-routing on this thing - why the constant u-turns?
Anyway, I wonder if you had went into the settings and changed the GPS settings for Navigation Preferences and unchecked the U-Turns and then tried re-routing? Was it any better?
My response:
i appreciate your response. please post a review on amazon, because i do think that magellan is trying to "bury" the bad reviews under their bogus reviews, and i think it's important for people to know before they purchase (in the same way you wish someone had warned you prior to your purchase.) i purposely did not turn off u-turns because i think it's an unacceptable solution: we shouldn't have to do that since there may be instances when a u-turn may be the best option. the original navteq magellan did not require me to turn off u-turns in order to re-route.

I have a TomTom and do Not have a U-Turn problem, I just re-routes and It uses Tele Atas maps. i think most of the problems is the way Magellan does the maps.

| Yes that's what I stressed above, the TeleAtlas maps are fine in the USA, as evidenced by the excellent routes provided by TomTom systems these days, it must be the way Magellan are using them, not that it matters to the end user, but there should be no hasty conclusions. |

| FWIW, TomTom's routing builds in a 5 minute penalty for U-turns, so that generally they're avoided even if U-turns are not set as an avoidance by the user. Unless Magellan did the same it probably explains much of what you're seeing. |

| the magellan navteq unit re-routes perfectly without resorting to u-turns, whereas the magellan teleatlas is flawed in that it u-turns rather than truly re-routing. |

| Understood. But there are differences in map attributes between Navteq and TeleAtlas. Perhaps something in the map metrics themselves is the reason for TT's U-turn penalty. Much smarter people than me would need to dig deep into attribute relationships to see how various pieces affect road segments and characteristics between the two map suppliers. But 5 minutes is a long time and would think TomTom had a very good reason for so aggressively avoiding U-Turns. It could be in the map. |

For what it's worth, this may be a failure on Magellan's part to properly match the software's usage of the map data to the format of that data. I know that when I first got it, the detour/re-route function on my 1475T was absolutely insanely stupid; I ran into a backup on I-30 just east of Texarkana, and headed for the exit ramp; on the ramp, I tapped the icon to get a detour route...and it told me to turn left and get back on I-30 in the opposite direction. I did that, but wondered what was going on, since I was pretty sure that there was a parallel old route nearby. At the next exit, it directed me to get off the freeway, and then to get back on to I-30 eastbound, which would merely have returned me to the same traffic jam I'd just left. The 2.20 and 2.22 firmware updates helped to alleviate this, but the detour function never achieved the level of utility that it needed. Recently, still running 2.22, upon approach to the Atchafalaya Basin causeway/bridge on I-10 westbound, I noted that the traffic was backed up all the way off the bridge; since there was a construction site that I knew about several miles ahead on the bridge, I figured that it was best to exit and take the back roads. No matter what selection I made from the menus to get an alternate route, it kept insisting upon putting me *back* on I-10 at the point where I'd exited, insisting that I had to take I-10 from that point before any detour could start...and then its detours were absolutely bizarre. I used my old paper maps to find an alternate route instead, and doubtless saved myself a couple of hours of sitting in traffic based on the comments overheard at a truck stop later.
A friend has one of the new, very-large-screen units (model, firmware and map version unknown), and it's even worse in this regard. The only way I was able to get it to forget its obsession with its original (and not well-selected) route from Trenton, TX to Texarkana, TX was to take it out of routing mode and run about 15 to 20 miles down US69 before telling it to route me to the destination; *then* it had me continue on US69 to I-30 instead of running me up to US82 and over through all those annoying little podunk towns. Until I did that, its reroutes just kept getting progressively more bizarre. On a different reroute, its approach was to have me exit from the freeway at every interchange and then *get back on* in the same direction; utterly, totally USELESS.
My 1475T is presently at Mitac's facility to get replaced by one that's not bricked; I just hope that the replacement isn't equipped with the same firmware and map data that made the other (newer, larger, fancier) unit infuriating. If it comes back with the kind of "upgrades" that will make it worthless, I'm going to drop back to using the atlas and other paper maps until Magellan gets their act together...if they ever can. |

don't hold your breath. i sent in my magellan teleatlas 3045-lm for a replacement and specifically requested the older firmware 1.41 and map 39 (navteq). magellan assured me that would comply with the request, but instead they sent me a unit with the exact same specs: map 41 (teleatlas) and firmware 3.11 (and had the exact same problems with traffic reception and poor routing/re-routing). when i called customer service, they said that there was no way to "downgrade" to firmware 1.41 and map 39. so i have a feeling they will not downgrade the firmware to an older version for you. you too will probably get the same "infuriating" problems again, as i did. time to switch to garmin... |

Warning : Magellan have changed to TeleAtlas (v41)
