| If someone hasn't said it, all you have to do is power the unit up after the USB is connected, and the PC will detect it. You can then proceed with the upgrade. Make sure you have the right plug on the AC adapter, and that the polarity is right! |

An update on my little RM500 saga: My loyal readers will recall that Magellan updated my firmware to version 3.20, saying that this would solve the problem of the unit occasionally forgetting all its user configurable settings (including all the addresses I repeatedly painstakingly punched in.) After a little more than two weeks in use with version 3.20, the unit has AGAIN forgotten all its settings and addresses. So, at least in my case, Ver. 3.20 did not fix this particular problem. Magellan's now sending me out a replacement unit.

As a followup to my RM Update, I too have remaining issues. The unit still resets (out of the blue) and will loose user settings. My address data, strangly enough, still is in place. But I only have about 4 or 5 entries in each of the USER1,2,3 profiles.
One new thing that has developed is I will Zoom the map to 1/2 Mile, pull into a parking lot, turn the unit off, then the car. Do my store thing, then get back into the car, start the car, turn the unit on and as I'm driving, the current map level will be at 1 Mile?
I'm calling Magellan today get an RMA for repair or replacement. |

| Further update: After only three days of use, the replacement unit has now lost its memory in exactly the same way the old one used to. Ironically, it happened as I started the car, departing from the United Parcel Service store, where I was dropping off the old unit for shipment back to Thales. It's not the CF card, since (1) the stuff it loses is not stored in the CF card, it's stored in the unit's internal memory; and (2) I'm using a different CF card. Could it POSSIBLY be something I'm doing? Any ideas? |

| Is your unit connected to a "accessory" power source, or an "ignition" power source. If it is accessory, that could be your problem. The transient on/off/on when turning your key apparently will do it, regardless of software. I had this problem when I first started using my RM connected to the cigarette lighter plug (accessory). When I hard wired to an "ignition" source, it never happened again. |

It's plugged into the cigarette lighter. Is the distinction you're making between "accessory" and "ignition" a distinction between "always on" and "switched"?

| Most lighters are in the accessory position on the ignition key (You can turn them on without turning the ignition on). That is the wrong place for a RM. |

| Formality. The instructions don't differentiate between types of power connections, nor methods of power up/down. Even when I attempt to follow a certain power cycle routine, the unit still fails in some manner. |

In my case, it seems pretty clear that the memory loss occurs either during the power up cycle or the power down cycle. I had a lengthy talk with a competent-sounding tech at Magellan; they are now trying to compile a list of the makes/models/years of cars where this is happening, thinking that it may have something to do with voltage or amperage fluctuations going to the unit as the car is being started, and that on some cars these fluctuations are more severe, or different in a relevant way, than on other cars.
LBOCEAN, your issue is different than mine, I think; my unit never resets while in use, but rather resets (loses memory) either during the shutdown or power up process. That is, it's fine when it shuts off, but has lost its mind when I power it back up. It seems sensible that if the problem is being caused during power up by irregular voltage going to the unit (momentarily too high or too low), a workaround would be to have the unit unplugged when you're starting the car. At least, that's what I'm going to try next (as well as, perhaps, rerouting power to my cigarette lighter so that it's "always on", as ekaxel suggests) I suppose the theory of "transient on/off/on" causing the problem -- rather than momentary high or low voltage -- could be tested by rapidly connecting/disconnecting/connecting the unit, and seeing if that causes memory loss.
If the problem really is related to voltage irregularities, I doubt they'd be able to fix it through firmware.
It might be interesting to find out the makes/models of cars belonging to people on this forum who are having this problem. Mine's a 2001 Saab 9/3 Viggen.

Akahan,
You're likely on the right track it sounds (granted I've been fortunate and haven't experienced that problem at all yet). I would be curious (in addition to wondering what particular vehicles are involved) if there is a common denominator in how they are wired, ie ACCY bus vs IGN bus. Being wired to the ACCY bus would be more likely to cause power-on problems, in my opinion, than being wired to the IGN bus *or* manually powering the unit on (has anyone experienced the issue when *not* using the auto power-on feature?)
An external solution might be had by using a time-delay relay which provides a few seconds delay before providing power to the unit. I'd be curious to know if this would solve the problem in any of these cases.
Here is an example of a delay-on-operate time delay relay which could be used for this purpose: (this one is rather expensive, however at about $60 US)
http://www.magnecraft.com/products/section4_11.pdf
You could adjust this for, say, 3 seconds, which would allow the voltage to stabilize before powering on the RM. Just a thought -
I'd be happy to try and find an affordable one if anyone wants to pursue the issue.
Cheers,
Brad |

The time delay relay is an interesting idea; I wonder if Magellan might, if it turns out this is the problem. build something like this into the cigarette lighter adapter. For now, I'm going to just make sure to have the unit unplugged when I'm turning the ignition on; if it retains its memory under those conditions for more than a few weeks, I'll have some confidence that we're on the right track here.

| I didn't say that the lighter was always on, only that it was usually wired to the "accessory" bus rather than the "ignition" bus. Things on the ignition bus don't experience the transient when the key moves between accessory and ignition. |

What type of loss of audio files does this update fix? After my last memory loss, I also lost all sound on my Roadmate 700. Could this update possibly fix this issue?
I have a laptop, so I could do the update in the car. Would it cause any problems to do this update while the Roadmate is plugged into the car, not a normal outlet?
Also, I intend to buy the extended warranty. Since there's a possibility that I have a defective unit, Magellan might send me a new one with a different serial number while my application for the extended warranty with the original serial number is in the mail. Has anyone had any experience with Magellan to say whether this would cause further headaches down the road - if so, I'll just wait till after the extended warranty has been purchased and approved. Since I think I have to purchase it within the first 90 days, I have to do this very soon.
Any advice is appreciated. |

FYI: 1993 Toyota Corolla LE (4 Door Sedan)
- Ign Off = A/C Power Off
- Ign (one click right) = A/C On
- Start Engine = Momentary loss of A/C (RM will go through restart process)
Regarding the warranty of the RM's.
I'm more than certain Magellan is aware there are a multitude of issues that range between the two product models. And that they are doing what can be done to resolve them. If updates don't work, perhaps a replacement model will. Maybe it will take 2 or 3, who knows.
In either case, with all the information that has been accumulating on this forum, it would be safe to say that Magellan would make every effort to get the unit(s) in full working order (less the map data, which is actually farmed out).
Simply put; You as a consumer have the right to a fully working/functional product. If it cannot be repaired, then you are intitled to a full refund.
Being involved in Consumer Protection for some time now, there is one thing that goes well beyond any warranty on any product. That being, Customer Satisfaction.
All this aside, as long as the MFG is making efforts to take care of the problems, which Magellan is technically doing by providing alternatives to remidy individual issues, the only thing to be concerned about would be if all the units are recalled.
Personal note: That would be the ultimate bummer of course, but with as many units out there that I'm guessing there are, I beleive it will simply be a matter of cycling out the problematic units with non-problematic units.
Side note: One thing to think about here, is that those who are on this forum, whom have provided feedback about there units, we've all become a collective of data, kinda like a beta test team (in a matter of speaking), which I think is cool.
We all become part of the solution :)

Dan:
Are you sure your interruption is between ign and start, and not between acc and ign. Sounds like cars that have a momentary interrupt between ign and start are prone to the problem. |
