I get to keep my factory cubby and now have a nice Android HU with all the useful bits you could want. Nav. Streaming Media. Backup Camera... Etc. This may not fit what you are trying to do so please do your homework. The factory Bose Speakers and Sub still function perfectly. Volume control is better attenuated in the Android HU by running Agama Car launcher as needed. Otherwise I am delighted with the results. Should be a factory option on any Double Din dash opening. Cost outlay is really minimal. Just a bit of soldering to get the wiring harnesses done.
