The factory front and rear park assist sensors connect to the GM CAN, and will display the park distances on the screen.
The factory park assist system automatically switches off the park assist once you drive over around 10Km/Hr...
The dealer fit park sensors for the back turn on when reverse is selected...
You could use the same system for the front, but you would have to manually switch it on and off manually when you wanted it...
The factory park assist system doesnt look too complicated in terms of wiring, the only thing your really need it the colour infotainment screen.

Sabath, I know what you mean...
I dont know why people need park assist, automatics, power steering, air conditioning, four wheel drive, abs, traction control, brake assist, stability management, a heater, lumbar support, adjustable seat, doors, roof, a boot, bonnet, reverse gear, windscreen wipers, and seat belts...
If you require any of these, then you shouldn't be ridng a motorcycle !!!!!
