navigation compatiblity
Is it just the display that isn't working? If I can suggest something, I would get a head unit and install that instead in its spot. Something with Apple car play is what I did and I use my phone as my gps.
Not sure exactly how mine was hooked up, but the a/c still works on my 06, just the display doesn't have power... but there is a mother thread where someone said it might be able to be powered up with a 9v battery... so could be a solution to that...
