Hi CL,

I have a 2007 IS350 and I recently had to replace my alternator and so during the process I unplugged the battery (both terminals). Once I got everything installed I started the car and the buttons on the cd changer part and the temp control buttons don't work. Only the tune **** works which is VERY strange. I have already checked all the fuses and even pulled out the whole nav unit to check all the wires and I can't seem to figure out how this all happened. Anyone ever encountered this problem or have an advice? Please help.

 

Pm me for direct contact, i could help you out

 

PM'd. Sunday bump

 

Solved! Just need to unplug the battery for about 30 mins and it's good to go.
