Picked up MX on 3/30 vin 89xxx with new MCU. 2016.10.6 pre installed. Took about 45 miles before AP kicked in. AP seems to work fine, lane change smooth. I tried almost all features and everything seems to be working. WiFi wasn't able to connect at 5GHz but worked fine after steering wheels reboot. FM, Streaming, Nav everything is working fine since past 4 days. Summon is kind of flaky, it takes my MX to half the garage then stops (possible because I have a steep entry for garage at about 30 degree, will test somewhere where garage is straight). Let me know if you guys think of anything that I missed and is not working will try to test ti.. btw, this is my first Tesla. And, yea installed IRO dash cam on first day, quality is acceptable if someone is looking for dashcam. on eday they sell for $250 ships from china (ships fast), I offered 185, but guy counter offered 200 + 15 shipping.. I bought that. Perfectly blends with car interior, looks factory setup.
