NAV System

[CarbonReptile]

Just wanted to update all of you on my NAV system woes. I recently had my routine servicing done, and mentioned to my Service Advisor that there is an update to the NAV software that will eliminate the infamous "T20.10" message. He was able to update the software. The system works nearly trouble free now (no more T20.10, just "=BMW=". I drove back from Miami yesterday (about 950 miles). The system worked great. I didn't notice any other updates to the system. Has anyone else seen anything?

That T20.10 is a software issue. I remember Mike posting about it 4 months ago. I believe the problem was that the Nav system unable to read the DVD. A simple software update will fix that error.
