on my MCS '09 I have an iphone 4 and the y cable but for some reason when i plug it it the phone doesn't charge... on the phone the symbol for charging is on (on the battery symbol) but I see the percentage go down... also my iphone sometimes wont go to the next song... and i cant control in on from the car controls only the iphone itself . I have to unplug it and start from the beginning again...


Is there a firmware update for this that i might be unaware of?
