[Droid Eris Android Development] Letitride:
Hmmm, kind of quiet on this thread on the newest V13 Vanilla release, so here's my 2 cents:

Update on V13 Vanilla - flashed this a few days ago, had issues with GPS FC's, frozen & reboot, etc. - pretty much the same story as that of Shed's GSB newest odex ROM, pretty frustrating, LOL - that's part of the "process" in ROM development. Doing a clean install, full SD card format, wipe system/cache/dalvik before flashing ROM & Gapps as recommended. From within NAV in Car Mode, Maps will locked up & stop updating within 10 or 15 minutes. Done all the tricks in tweaking except flashing one of the fixes posted in one of Tazz's threads, even NAND restore back to an earlier version & with/out the latest Google Maps update ....

Now back on CS's V13 ROM, after a full SD/system wipe, NAND restored to my last V12 with minimal problems running Google Map, did a cache/dalvik wipe & flashed V13 Vanilla - AND, I also flashed the March 2011 Gapps instead of the newest June 2011 Gapps - then setup my Apps by re-downloaded them from the Market .... took a while. Put Google Maps/Navigation to the test earlier today on north via the parkway and CT Turnpike - Maps stopped updating but at least it didn't result in a reboot. Was able to restart it & re-lock GPS (without "Searching for GPS ....") after I turned off "Use GPS satellites" under Location & security settings - so, NAV was at least usable for the last 20 minutes of the trip this morning with the Maps updating its distance/time to destination as we're cruising 70 mph.

I've more update tomorrow/Tuesday when we head back to NY after the holiday with the Eris navigation. Cheers & Happy 4th of July to all, and, thanks again - CS, much obliged for your work. :D

Postscript/Update - We drove 140+ miles late last night down I-95 back to NY, experimented with turning on/off one or both - "Use wireless networks" & "Use GPS satellites" and also flashed the GPS fix posted elsewere here to see if Google NAV/Maps will do any better. Well, everything worked for about 10 or 15 minutes, then the map screen stopped updating location - BUT - time/distance to destination including turns continued to change/update. Tried to exit the Apps but it froze with FC/wait message screen without going into reboot - somehow, it managed to find GPS signal(s) again & resume, and I just let it ran - without the map location being updated in real-time, but announcement about exits/turns stayed on correctly, even when I detoured off the parkway and onto local streets to drop someone off, and it "navigated correctly" via local streets (it was the shortest route then) to the 2nd. interim stop, before we headed home. To sum it up all, it seemed as if the graphics display were not getting refreshed on screen but that tracking with voice turns-by-turns managed to stay accurate 98% of the time on my latest run - didn't FC or reboot as long as I left it alone. Maybe the CPU overclocking on GB ROM is pushing the Eris too far ??? but my was maxed at 604/245

Anyone else have any extended observation on GPS usage to share .... Until I decide what to do with my regular Garmin GPS unit (thinking about upsizing from a 4.3" to a 5" screen) replacement as the 4 years old unit finally bit the dust, LOL.
