I owned a 1gen 900BT for about 15 months until last week when it was stolen. I recall reading a fair number of buyer's regret on the F-Series, (mostly technical functionality). I wanted to seek a few opinions on what to replace my 900BT with: another Pioneer unit with fewer of the issues, and more functionality? or another brand/model even with stronger record of performance/satisfaction?

if you liked your unit, then check out the x920, its a lot of the same and also better, (supposedly they fixed alot of the software issues with the newer model )

kenwoods still have a few issues themselves but there nav is much easier to use, but there GUI looks years behind, alpine or eclipse would be the two top choices for quality and just overall good a$$ players if you dont mind spending a few $$ but then again good deals can be found on everything on the internet
