i have a alpine car stereo that came with the ipod cable... i have a 32gb ipod touch that i attach to the head unit...

i control ipod through the head unit..recently (after 4.0 update) it has been running really slow through the head unit...i deleted all my apps on it and now just have music...still really slow...
anyone have any input on to why all of a sudden this is happening.

thanks
chris
