If you don't mind changing it up, then you have a variety of options. Unfortunately, most are made more difficult due to the stock Bose equipment. Best bet is to rip everything out and install a new double din HU that does whatever you want it to do (Kenwood or Pioneer seem to be the most popular). It will installed be down lower where the audio controls are. You could also put in a less expensive aftermarket audio system and HU and put a tablet where the Nav screen was. None of these will be as good looking as OEM Nav IMO, but they have far more potential. It's all about what you want.
