ok.... i have decided i want a Blinder to go with my X50 instead of the Zr3. The only thing is that i want SOME kind of rear protection, just in case. i dont think i should spend all this money on a jammer and get hit where it hurts and get a ticket. so i decided i need an M40 to cover the rear of my dodge neon. the thing is i cant spend the 750 that it is to get it with an installcard from roy (ZR3 plus install=500). i have a friend who is a great mechanic, and i want to know how hard it really is to get the system in and working. i know the jammers have to be level, but thats not the biggest problem i assume..... anything i should know before i ask him if hes up to the task?
