i have a kenwood kdc v7521, yea its wuite old but it looks teh nuts.
anyway i got this with a car i just bought but cant seem to work it.
i plug it in and all it does is the screen changes colour on its own and the buttons dont do anything. is it some sort of security feature or is it bollocksed? cheers
also i installed my sub yesterday and whilst adjusting the bass on my amp it kept sort of popping like it was getting to much power, it jumper to fook!
