After playing with the Tomtom some more, reading number of forums, and upgrading to the official bootloader, here's my consolidated list of improvements/problems that I found in 8.350. I excluded things that seemed to affect only one person.
Note that the app was pulled for 740 users (at least in North America).
Confirmed improvements:
- fm transmission of instructions, but only when playing music
- floating icons in browse mode - arrows to home, destination, and current location
- advanced screen in browse mode preferences, with option to disable above icons (markers)
- tts voice in route demo speaks at 400% speed now, up from a max of 200% in 8.302
- able to add rotaries in mapshare realtime - will not show rotary on map, but will show a rotary in the turn arrows, and say "cross the rotary" in route mode
- fixed metric rounding error in mapshare
- fixed hidden turn restrictions in mapshare
- music/audiobooks resume from where they left off after being interrupted by directions, you no longer miss a piece of the music
Reported improvements but unabe to test:
- blackberry phonebook import (don't have a blackberry)
- LIVE traffic works in Operate my GO (don't have LIVE traffic)
- lowered (non distorting) line out volume (don't use line out)
Confirmed changes (good for some, bad for others)
- max volume reduced 20% from app 8.302, no longer distorts on high volume while on battery. For anyone upgrading from app 8.204/8.310/8.312, the max volume reduced 40%
- changed Bluetooth code. Better pairing/connections for some (like me), worse for others.
Confirmed new problems:
- new screen flicker / river artifacts (only after bootloader upgrade)
- slower route planning when using an SD card, no change when using internal memory
- battery status indicator drops to 90% immediately upon disconnect from power
Reported new problems but unable to test:
- 3rd party programs no longer work, workaround is known and 3rd party developers are making app upgrades
Reported new problems that I didn't have:
- cannot download new voices in HOME (seems to only impact those who previously had the 8.320 hack, try deleting the entire Loquendo and voices folder and reinstall the app)
Confirmed installation issues:
- long time for initial satellite fix (typical of new software upgrade). Afterwards it works normally.
Installation issues that I couldn't test:
- additional HOME disconnect required to see INTERNAL vs EXTERNAL memory (don't use an SD card, didn't happen to me)
- additional HOME disconnect required to use Operate my GO (probably related to INTERNAL vs EXTERNAL issue)
- repeated pin resets required to see phonebook (my phone doesn't support phonebook transfer)
