I use my N900 with builtin car kit in a new Renault Megane. Before PR1.2 upgrade it worked perfectly, both for handsfree calls and A2DP streaming.

Now, with PR1.2 A2DP still works fine, and all handsfree works ok EXCEPT no audio comes from phone to car kit (voice out works clear apparently).

This obviously means its useless for car, which is a real pain for me...

I updated using OTA method, I'm going to try and re-flash clean to see if that helps...

I've heard going back to PR1.1.1 is not possible, is this true, does anyone know?
