I'm selling my Hualingan fitted in my E39 before. This unit suitable for X5 too. Design for both BMW. Direct fitting. No modification or wire cutting. I'm selling it for RM1000. "SOLD" The units running fine but I decided to give it a try to Android based device. Google Hualingan or search in this forum for details of the unit.
No taker? Price drop to RM1000. Clearing my space guys. Comparing against my new Android based, I kind of like Hualingan due to boot up speed (Android too slow to boot up) and Hualingan has more features. Hualingan is running on Win CE. Here sample on how the device looks like. http://www.xoutpost.com/attachments/x5-e53-forum/45081d1287284079-install-hualingan-e39-e53-diy-hualingan-pic.jpg
