I installed the viper GC and have the following issue: I never got the initial BIOS screen... had to program cobra 2.1 using the USB - which worked. Now, when I have the Viper enabled and power on the GC: one of three things happens: a) the drive SOMETIMES comes on and the screen stays blue - nothing else happens. b) it boots into Cobra and works fine c) it boots into normal GC mode and runs like a non-viper GC. When I try holding down A, X or Y and SOMETIMES the Cobra interface turns on when I power the unit. When I do get the interface to come up, it does work fine. If I disable the Viper, it goes straight into the normal mode and works fine. I have looked at the install using a magnifiying glass but I can't find any problems with the wiring. Any ides on this? Does it sound like a wiring problem or a bad Viper and which wire should I be checking?
