Thanks, Peter. I have the Garmin City Navigator NTU for Europe that I purchased last year before our ride around Catalunya. I updated the map last week, so, hopefully, this will be 90% consistent with the HERE planning map in MRA. The places where we really care what the route is don't have a lot of intersections, so hopefully 90% accurate will be good enough. My riding partners will all use gpx maps that I have created, and they have Zumo XTs, so I think I will follow them and hope for the best. I really am bringing my Garmin just as a last resort option. If I am in the middle of nowhere and I can't get MRA to work, at least Garmin should be able to get me back to the hotel with a direct route. Fingers crossed, anyway.
Yes, my zumo 396 is five years old. I have been reluctant to spend the $500 - $600 US for a Zumo XT, plus I would have to buy another map for Europe since Garmin will not let me transfer the map from my 396. I have been hoping that MRA will mature along with the Android Auto devices and I can retire Garmin. I think the technology is not yet stable enough for that, today, though.
Good idea to put basecamp on the laptop! I was hoping I was done wrestling with Basecamp, but you are right that it is probably the most reliable way to see what is happening with a Garmin map and getting it on my Zumo 396.
I think I have figured out how to mount the Garmin on the rental bike using a Ram claw and a finger grip Ram phone mount. The hardest part was power -- there is no room to plug a USB power cable into the back of the Garmin when it is on a generic RAM mount. I got creative with a saw, though, and made some room!
Thanks again,
Vinnie
