boxhead,
Steer clear of the immobiliser that requires you to touch the fob to the dash mounted sensor. Thats what I have and its a pain. Get a good remote unit. Naturally get the COBRA brand or go for the Mongoose brand and really confuse your Cobra.
Hang out for Mikes advice on the seat belt light. What he came up with is a Gem....like usual.
Regards,
Phil
