Not everyone knows about that site, obviously, otherwise the OP might have already considered that.
To get back to the topic on hand, I am using a Continental single DIN stereo with bluetooth, and then I run Headunit Reloaded on my phone if I want Android Auto. I made a phone mount out of some sheet metal and some spare parts I had (best photo I have at the moment is below). Most of the time I don't even have the radio on.
