Garmin nüvi: official Volvo retrofit

Dear elk forum In February there is an accessory action in the CH for retrofitting a Navi Garmin nüvi incl. holder, cabling etc.; looks very clean, no cables, good integration into the audio system, Bluetooth for your mobile phone etc. What do you think about it? Has someone already had it installed and can at best already give a review? Thank you and always good ride timbi
