I tried to search but RHB is too small or too few letters. Has anyone been able to perform this swap? I read one thread that said it would not fit & another that said it will. My Ram has the base radio & I want good GPS as well as the Sirius with the buffer option that the RHB offers. I can't even find an aftermarket radio with Garmin Nav & Sirius buffer or I would get that. Any help is appreciated!
