after taking a spin this morning with a new TomTom car kit, i can confirm that my 3GS with Navigon 1.4, fixed price traffic service, free google search, and TT car kit ... unbeatable! 
p.s. i found no issues with mount moving after hitting bumps (granted there is a limit to that test) ... also, the mount needs to be shifted to the middle notch and power line probably should not cause any weight (or tug) on mount; i have power line running up thd side of dash, wedged into molding allowing no weight on mount |

So w/ the launch of 2 "enhanced GPS" mounts for iPhone (TomTom and Magellan), does anyone else think, or anticipate, that these mounts will become targets for theft? ... they cost about the same as a lower end PND. What think?
Any suggestions for theft proofing; other than removing the suction every time parked in public lot or on street? |

I don't know why beanbag mounts aren't more popular than the windshield mounts.
For one thing, windshield mounts are illegal in some states.
For another, iPhone is not going to be left in the car like a PND might so the use of the iPhone/mount is always going to be temporary. Bean bag mounts are better for this kind of use, not to mention easier to put away and hide. |

after using TomTom car kit for a few days, i think i'll really like it due to the combination of power, speaker, GPS and ease of use ...
one thing that i'm curious about is whether there is any way to confirm that my satnav app is actually using the car kit's GPS. the reason i ask is that i've noticed that it takes the mount 20-30 seconds to achieve a fix from a cold start (by using the free TT car kit app) ... but the iPhone's fix is quicker due to the assisted GPS approch ...
which fix will the satnav use?
i've tried to test whether removing the phone during navigation disrupts the GPS fix for a few moments as it transitions from mount to phone GPS ... but i am getting no disruption. just causes me to wonder whether satnav app is using mount GPS
any thoughts? thanks!
btw, this goes for the Magellan car kit as well ... |

after a few days of experimenting, looks like it behaves like this:
since it takes 20-30 sec for TT mount to secure a fix from cold boot, the satnav app will secure a fix w/in 8-10 seconds of cold boot - most likely from iPhone assist GPS ... then about 30 seconds into navigatin, there is a momentary lag on tracking which i assume it's switching over to mount GPS from assisted ... also, if you remove phone from mount while navigatin, it does lag on the switch over to iPhone assist GPS.
so i guess behaves as suspected, just took a little to see the actual behavior
would be nice to be more factual |

Did you try the app? I did today and while it shows Cellular/WiFi separately, it shows GPS both for the internal and external GPS.
The main thing is that that we get the best possible location source based on what's available. |

I have used the GPSinfo app a few times and can see the cellular/wi-fi and GPS, but it isn't distinguishing "internal vs. external" ... maybe i'm missing something. I did cross check the Lat/Long between Navigon, TT kit, and GPSinfo ... and all were very close when mount had secured a fix. it was a little hard to compare during the first 30 seconds of cold boot to cross check that Navigon was using iPhone initially before mount fix, but most likely the case.
Thanks for suggesting. |

As I have monitored the 'enhanced GPS' capability of the TomTom car kit, I noticed that the "accuracy" of the fix improves though not as much as I would have expected, or liked. Seems as though the iPhone GPS fix has an accuracy of about 17m (56ft) and the TT mount GPS fix improves to 15m (49ft) while moving/driving ... not much, although I guess it covers the marketing statements.
Any other related observations?

Keep in mind that these are just estimates as on the Garmin systems and I had shown in the "GPS accuracy" article on the portal that it can only be trusted to a point.
Having said that, uncorrected GPS accuracy is about 5 meters in a perfect environment and with professional equipment like the one currently featured in GpsPasSion Live (www.naviblog.com) so with a tiny antenna in town with bounced signals (multipath) you can't expect better than 15 to 20 meters and that's handled fine by the navigation software with tricks like "snap to road". |

From TomTom support on Friday 6/11 When asked if the car kit will work with the Iphone 4.
apprehend that you wish to know whether the TomTom car kit is compatible with iPhone 4G.quote:
I understand how important this is for you. Please be assured that I will definitely help you with this.
David, the TomTom car kit is currently available only for the regular iPhone, iPhone 3G and iPhone 3G S. The iPhone 4G being a newly launched product from Apple, it has not been tested yet with the TomTom car kit. Hence we regret that we will not be able to comment on its compatibility with iPhone 4G as there are some significant size differences between the two models.
We are receiving lot of requests from customers regarding the same query and we have already forwarded them to our Product Development team for further review. We take all customer feedback received very seriously in the future development of our products. Suggestions are gathered and organized to understand the areas our customers are most interested in enhancing.
Our Product Managers review all feedback to determine future enhancements and products. Many of our current products and updates offer features based on customer suggestions.

Thanks for sharing, been wondering about that too. Clearly Apple didn't give TomTom any info on future designs when the Car Kit was designed...too bad, I remember that in the days of the iPaq GPS sleeves, ALK and TransplantGPS had been given a guarantee that there would be at least another generationof iPaq's that would be compatible...and it turned out to be the case 37xx, 39xx and 54xx.
Anyway, looking at the official specs there is hope as the height it virtually identical :
- iPhone 4: 115.2 x 58.6 x 9.3 mm / 137 gr.
- iPhone 3GS: 115.5 x 62.1 x 12.3 mm / 135 gr.
We'll soon find out for sure ! |
