I'm trying to upgrade radio to a touchscreen with navigation & cd player I want an oem radio not sure which unit I can upgrade looking at model 9L1T-18T805AA does anyone what I can upgrade to
The original radio that was installed model #9L8T-19C157-CB no display/navigation installed model #9L8T-18K931-AG which seems to work radio, gps, bluetooth, only problem having is with the sound/volume is very low, any ideas why this is happening or what I can do to fix it, I appreciate all info/advice your giving meI understand what you are trying to do. If only it as simple as plugging in an upgraded radio head and life would be good. It's not that simple. A lot of research, time and money. First, you need to identify the level of entertainment system currently installed, with all its subsystems. Next, wiring a diagram and with all the connector views. Then you'll need a wiring diagram of the new radio head and it's subsystems. Will you have all the necessary wiring and connectors in the vehicle for the upgrade? Most likely, not. Pull the current radio and post the part #. Better to take some pictures of the radio label and faceplate. Post some pictures of the radio connectors. Post some pictures of the radio you wish to upgrade to. Do you currently have a factory Amp? Subwoofer? Navigation? I posted 2 diagrams. One is the basic system, and the other is a factory higher end system. See the difference in the subsystems in order to make it work. View attachment 3169 View attachment 3170
