Well you two have been busy while I was snoozing.

Since it still isn't working lets try to go over it all looking for whats missing.

First what did you have before the install.

Factory nav or mid display?

What have you removed that was factory?

Front display if it was nav?

Cd changer? Bluetooth module? Anything else?
