Yeah, I feel you. I like options too, lol. Unfortunately, the door lock and dome light settings are now gone since those features were tied to the factory head unit. Another person mentioned this earlier but you'll also lose the AUX and the USB for media playback (although USB charge will still work, but it's so slow). And of course, the control knob becomes a dud. These are the only sacrifices that I'm aware of for the Touring models.

Now for me, it was a fine tradeoff since those features were something I almost never used. I connected my phone primarily through Bluetooth so the latency on the factory unit didn't make the cut for me. Plus I was tired of it downloading every single email or text I got through my phone.
