I hope someone can help me, my installer is less than a professional. I need to get the Illumination wire hooked up, this unit is blinding at night. He was feeding me some bull about auto dimming, I called Pioneer no such thing. I am going back in a couple days and want to make sure it is right this time.
He has really screwed up things, heres a list of problems so far...
No warning Chimes for seatbelts ect....
Voice guidence keeps talking after I turn it off
No memory seat chirps when set
Steering wheel controls quit after a day
Illumination wire not hooked up
On my first trip to check Nav all volume for unit just quit, no radio, Ipod Nav, radio
VSS not hooked up
I'm pretty pissed 
, he says he'll fix everything to my satisfaction. If not I guess I'll call credit card company dispute and find another qualified shop in Fort Lauderdale. There has to be one.
