Thank you for your Zumo XT report BoulderTed! The more I’m reading about Nav 6 issues, the less I’m willing to consider it. Some people rave about the Nav 6 ability to provide telemetry information, and the wonder wheel interface, but I don’t think this is important to me. I’d rather have a solid GPS like the Zumo XT, than taking my chance with the Nav 6.I went through the same dilemma on my recent purchase of my 1250GS. Garmin is no longer partnered with BMW, I assume because BMW is integrating a nav system in their TFT. So I don't think the Nav VI will be around much longer.
