So, when you want to change setting on the Corvette Alpine it requires that the handbrake be in use. As it turns out the dang wiring for this feature was never hooked up.

I purchased a module that simulates the handbrake and brake pedal activation is in use. This allows you to access the setting section.

This was needed if you want to turn off all the warnings the GPS send out, mainly the over speed limit warning which I was constantly hearing.

The stereo was completely ghetto wired, too many shortcuts and cheap connectors used. I was able to identify most of the interior wiring except the power antenna activation signal. I looked all over and no luck.
