Guys - help me out here....why are options 'greyed' out like Navi Settings, System Settings, Dial Pad, etc...(this is for my Pioneer F700BT)

My car was not on but in 'park' mode. I thought maybe this was greyed out due to safety when the car was being driven, but it happens all the time. I tried this with the key in the ignition, and car not turned on as well as tried it in the ignition with the car in 'park' mode. What is the 'speed unlock'?

I have seen all of this work in the past with the sellers phone when he was selling me the car. Very confused...

Thoughts?

I too am looking for this fix

Engage the parking brake, or do a bypass.

Push in the emergency brake.

every time or just once...

Every time, or do the bypass. There's two types of bypass you can do to the unit. Either way will achieve the same results.

The first is the hardwire bypass shown here. http://www.avic411.com/forum/viewtopic.php?t=17013

The second is the software bypass shown here.
