Been running the Garmin XT for the last few months, Fitted in the Original Nav 6 mount. I find it 100 times better, in everyway over the Nav 6. I very rarely used the selection wheel with the Nav, so don't miss that. The Maps in Topo are great, clear and detailed. The message notification panel. I like it. I cant think of any negatives. Great bit of kit.
And half the price of a BMW unit.
