I have a 04 TSX and the navigation screen is not functioning. Will I be able to install the 07 one? Thanks

 

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.

 

How do you adjust the AC as the unit is integrated with the oem gps? Thanks

 

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...
