anybody give me some pointers..gunna fit my alpine headunit in me car...in the instruction manual it says to be sure to disconnect the (- ) from the batter before fitting... should i disconnect this before removing the current unit too? and do i need to do anything to the car once its installed and ive connected the (-) back up? like re-sync the key or something?
cars got a standard anti-theat system.
im a total n00b and dont wanna do anything wrong like disable the cars security system or anything.
cheers for any help =)
