there is a minor wounds inside the glovebox 6NF but not visible if I close the lid or add the phone adapter. It shouldn't be required to remove (well, cost of a guinea pig).
Overall he has been good. The most scary part is removal of the shark fin antenna and replacement of GPS included antenna.
The HU has a sirius label so I believe it's for EU market. He said he'll try to hack the unit for asian languages or order another one for me. Not sure if he's getting one from China directly. Taobao has some sellers selling HU too, I dare not to try as they seems to be selling EU ones too.
