AM/FM works great. I use Spotify Premium and download my music so I always have it. This has worked flawlessly so far. I also downloaded a large area around me on Google Maps, although I usually use my phone as a hotspot.
Torque connects quickly and works well with my obd2 connection. I see a report talking about this not working. It's possible that I happen to have the correct OBD2 connector type. I know there are some that say they may not work on Android head units.
I also ran all 3 USB connections under my dash. It runs with my charger and dash cam with no issues.
So far I've been VERY happy with my purchase after about a week. I was concerned as there was only one review with no reviews written at the time.
Now for the bad stuff.
There really isn't anything bad, just something different.
My other gripe is that you can't seem to customize the widgets on the home page. It has the clock and radio controls, which are nice, but I can't move them or even place the Spotify widget on the device. It's not a big deal and only takes a minute to get used to.
Overall I would definitely buy this again. I would recommend this to anyone looking for an Android deck.
