[FONT="]I did the MIB2 conversion in our 2015 Sportwagen S last summer and have no regrets: I paid about $680 for everything (hardware, programming, shipping, etc) but it is not a trivial process so read the info in
this link if you are interested in that option. The MIB2 hardware from any base 2016-17 MK7 (screen, head unit and USB Port) are direct swap for the MIB1 hardware in your car.[/FONT]
[FONT="]I heartily recommend the OEM upgrade as it is well worth the time & effort![/FONT]

[FONT="]Base MIB2 keeps all OEM controls, menus, car interface etc. Adds faster response & better audio, higher resolution 6.5" screen vs 5.7", adds Android Auto and Apple Carplay so you get NAV and more by using your phone and the maps never need to be updated!

[FONT="] Aftermarket is not an easy solution either: You will likely have to pay extra to keep steering wheel controls, ALL car related menus, etc from the OEM unit will be gone and you will need to “modify” the dash to make it fit. [/FONT]

[FONT="]If you replace the stock MIB1 head unit with another one you will still have to go to the dealer to have Component Protection removed and the head unit coded to your VIN (this is not a VCDS thing) but they can do it easily. The screens can just be swapped with no programming, but with the high failure rate of the early MIB1s I suspect the issue is probably in the head unit.

[FONT="]I still have the MIB1 unit from our car: It was replaced under warranty because the original went bad right after we bought the car new in April 2017. The replacement head unit has a build date of 2017 so it is the "later" version from a different manufacturer and supposedly not as prone to issues as the early ones. It was working flawlessly when I removed it last September. PM me if you are interested, $75 to your door for the complete kit: screen, head unit, MID/aux port and manuals. Staying with the MIB1 is hands down the quickest and least expensive solution, but look into the MIB2 swap! HTH[/FONT]
