NTG 2.5 unit for 06 CLS 500?
I have an 06 CLS 500 with stock audio unit (no nav, no phone, no bluetooth, no nothing). I've found a 2009 european ntg 2.5 unit on ebay and was wondering if there's any issues getting it to work and what kind of hassle/nightmare I can expect for activating the unit and also loading US maps on it.
I've seen a few threads around ntg 2.5 retrofits but it seemed those were US units.
Any suggestions/ideas or otherwise would be greatly appreciated.
Thx.
