is there anyway to get around the lock when you dock to a car stereo? for example when i dock with my pioneer headunit the headunit automatically locks you out of the music and movie control on your ipod and says external device connected. well what i want to do is to watch movies while its plugged in and send the sound out to the headunit. now i could be simple and send the sound out through the headphone jack but then it wont charge off the headunit. as modifiable as the the touch is, im sure there has to be be someway around this lockout. can anyone help?!
