alarm probs continue

[boycarp]

still can't get the alarm to arm and the head light warning buzzer doesn't sound, haven't had time to put the old head unit back in but i'm sure this is the problem that i have out a new head unit in fuse if fine beacuse the interior lights work and the alarm led flashes when u disarm the interior sensors, also the interior lights come pon when u open the doors and unlock the car but they don't come on when u switch the engine off.

anyone had this problem after installing an after market head unit??????

doing me head in now.lol
