09 E63 Radio/Nav upgrade?/Backup Cameras
IMO, not worth it (over 1k in parts). i personally am using a tablet linked to bluetooth Viseeo adapter. the tablet is magnetically mounted to the CD Slot.




Consider looking at the Android version which has a lot more flexibility and newer functions (touch screen) and you can install lot's of Android apps. It is not quite as seamless and has a couple of quirks (for example when you change menu items on the instrument cluster, sometimes the music will change track too ... this could be a setup issue though). Also, it takes a while for the system to boot and to hear music/radio etc.... Anyway, this is a lot easier to install (still significant for those with Harmon Kardon) but not bad at all. I have this on my E320 CDI and it is pretty decent overall.
If I had to pick one now, I would probably pick the Android version based on cost and flexibility. Old Android versions were not up to snuff but the recent ones are not bad at all. Back when I did my E55 though, I would have picked NTG 2.5 for sure.
