I have had the exact problem happen to me as well. I have been running V2B2 and quite often (and randomly) the ipod screen will freeze (music still plays). I loose all controls from the car and sometimes I can't even soft reboot my ipod. Another thing I have expereinced is that sometimes it will just switch over to AUX1 and no longer have text display too.

I am getting quite frustrated with these glitches.

I have tried reverting back to the 2.07 SW, but have even more problems. Now the Ice LInk dosen't even play music anymore when it's plugged in. Is there away to reconfigure the firmware that is found on the IceLink??
