What features specifically are you looking for? If you plan to use a phone, i'm assuming this won't be in the dash?
What is good about timur's rom is that it powers on and off with the car because the power button is not accessible and has a few battery tweaks. Besides that, it's just a regular android OS. I don't see why you can't run an OTG cable to your smart phone, purchase BTSSM software, etc...
