2006 lincoln Navigator with oem nav and THX sound system

[junbug79]

My friend ask me to help him install his aftermarket head unit in his 06' navigator with the oem nav and THX amplified system. Problem
is we cant find a wire harness made for the 06" THX system. He has a metra 70-5521 wire harness already, but I don't think it works with
his setup. Are they any options since there looks like there is no harness available for this? he just want to add only aftermarket navigation double din head unit, no aftermarket speakers and amps. Thanks

junbug79, did yawesome OTEigure this out? I'm having the same issues.

I just ended up using an aftermarket 15" flip down unit instead. I installed
it in place of the oem unit. Now it has awsome sound.
