My setup:
- Sprint Vogue
- Leaked 6.1 ROM
- Ran PPST.exe / Gets locks quick
- Garmin 4.20.50wp w/ 2009 maps

My experience:
GPS worked great most of the time. I had it plugged into a car charger the whole time, so I'm not sure about battery drain. I had the audio routed to my BT Moto T505 the whole time. Started Garmin up, got a lock in under a minute, gave me a good route. On the to-trip it never lost sat reception. The only issue I had on the to-trip was when there was a section of road when it kept recalculating even though I was on the road it told me to go on (it was ramps from one interstate to another). This could have been the Garmin maps though and not the GPS.

I had it setup to avoid traffic. Once I get near St. Louis and golden diamond popped up on the map and I tapped it and it gave me an alternate route around a traffic jam. I really like that feature!

On the return-trip, it said it "lost satellite reception" once, but it picked it back up within a minute.

I had the phone in a car-mount, so it was near the front of the car the entire time.

Overall I'm very happy with GPS and Garmin. It works as good as my BT GPS unit did. I do wish Garmin would announce street names like iGuidance v4 did, but I would much rather have the Garmin interface than the iGuidance one.
