So when I bought the TSX the navigation touch screen was non responsive. After starting the car, it would go to the screen where you enter the security code and eventually just dim/turn off since the code couldn’t be entered. The set of buttons under the nav screen and the little toggle switch also did not work. The climate control buttons to each side of the screen worked though.
After doing some research online, I came across the conclusion that maybe replacing the whole touch screen unit would do the trick. So after $370, I ordered a unit from eBay.
So after I received it I prepared to remove and replace the unit currently in the car. While doing so I noticed a white plug receptacle on the under side of the unit. The previous owner mentioned something about a white plug in that area that was for the light assembly of the cubby that was replaced by the Clarion head unit. I didn’t see the white plug off the bat and looked around for it. It was tucked off to the side of the Clarion head unit. After taking a look at the plug and receptacle on the OEM unit I began to think that it wasn’t just for a light assembly. There were too many contacts inside to just be for a light. So I connected that white plug to the under side receptacle of the OEM touch screen assembly and started the car… And what the friggin hell do ya know?! The touch screen works! >=(
So…expensive lesson learned. I’ll only be out the 25% restocking fee the eBay seller charges after I return the unit. =|
The newly discovered problem? There is a navigation disc error. So I ordered the final map update release for the 2004-2005 TSX that came out in 2014. The 2014 Orange DVD Map update V3.D0 is the last update for my model year TSX.
Hopefully that will fix the navigation system of my used TSX.
