10/29/2007 PLEASE NOTE... This procedure predates the official Navcore 7.x upgrade for TomTom One version 2 with serial numbers beginning with an "E".
First of all... Thanks to toni2047 for steering me in the right direction.
Here is a working method to finally upgrade your TT1 v2 with the SiRFFIII chip set and a serial number that begins with "E".
NOTE! No maps are provided by this upgrade. TomTom has not made them available at this time.
REQUIRED! You must use TomTom Home 1.5. http://www.tomtom.com/plus/service.php?ID=17
REQUIRED! You must have a card reader installed on, or connected to, your computer.
IMPORTANT! This process may not work if your TT1 is attached to your computer. You will be working with the SD card exclusively.
VERY IMPORTANT! Do a full backup of your TT1 first.
UPGRADE PROCESS:
1. Remove the SD card from your One and insert it in the card reader.
2. Start TomTom Home 1.5. The SD card will be discovered by Home.
3. On the Home menu, select Device | Change device
4. In the "Select a device" window, click the "Change target device" button at the lower left of the window.
5. A window with several device types will pop up.
6. Select the third instance of "TomTom ONE New Edition" and click OK.
7. The familiar Update/Upgrade search will be performed.
8. Deselect all but QuickFix and the TomTom application items. Do not upgrade the Home application or any maps!
9. Perform the download normally. You will be prompted to do a backup...but you've already done that...RIGHT?
10. The SD card will be accessed and the old data will be replaced.
11. If all goes well, you're finished. Install the SD card in your disconnected TT1 and do some testing.
Afterthoughts:
I made the upgrade to the very first backup of my device. All of the add-ons (Suntime, modified menus, custom start-up and shut-down graphics, custom POIs) were not installed. You can experiment here if you like, however I think it is wise to keep the upgrade process as uncomplicated as possible. A backup immediately after the upgrade is good insurance.
As soon as I get some real-world testing done, I'll see about restoring the customizations.
That's it!
