Parking Assist not Working

[FYRCITY]

Has anyone had any problems with their parking assist after installing an after market nav system? I have a 2007 tahoe LTZ I removed the factory NAV and had installed a Pioneer Avic-Z2 with Rear camara, Bluetooth, and Ipod Interface. Since then, the rear sensors are not exactly working right and the three assist lights on rear post are not working. Any Ideas?

I can only suggest that you check the Park Assist button on the dash. You can turn it on and off, I'm sure you already knew that.
Best of luck

Yeah, that was the first thing I did. The guy that installed the system I was not too happy with and had no clue as to why it was not working. Although he did do a good job... Long story. I was not sure if somehow the system was tied into the factory system I took out somehow. I am considering selling old system... FYI it was never used...except to get me to the radio shop to take it out.. I will let you know
