Boy oh boy I would honestly swap to an aftermarket HU hands down. I wish I didnt had the RF headunit so I can install an nice aftermarket one without cutting features that comes with my factory one ( Like backup camera). I know other features like bluetooth, navi and even steering wheel controls can be retain but not the camera and I'm not willing to wire a new one. So take advange of that and get a nice head unit like the Pioneer Appradio or something like that. If you want to add an amp later it will be a breeze. Right now Im having a hard figuring out how to wire a new amp for my speakers and make a clean install out of it.
