I've been considering this also. My research to date shows that it is entirely possible to install backup sensors, the display on the headliner and the control module. Where it becomes a problem is integrating it with the radio. The module itself doesn't communicate on the class 2 serial data bus. It connects to an input on a BCM and as you get close to an object, the BCM sends a class 2 signal to the radio to activate the chime. The problem is that the Bonneville RIM doesn't have this input. The Cadillac DeVille RIM is very close to the Bonneville in many respects. It does support this input. The DeVille RIM also supports many of the other options such as ALC which the Bonneville has (and is ALMOST pin for pin compatible). These two cars (the GXP and DeVille) already share several components. I may try installing a DeVille RIM as a test, but it doesn't support the accessory inflator (which I really don't want to give up). I can make the system work, with the exception of the audible chime. I'm just not sure I want to add this if I can't make it work 100% the way it was designed.
Haro suggested RainSense wipers which is another one I'm looking into further.
