MRA is really my only option, as I can't, and I've tried a couple of methods, get Basecamp to run on my Linux PC.

My XT is playing up too. It'll take me up a side road, then tell me to do a u-turn to get me back on the route. I use MRA, and for now I'm simply following the track it produces.

Those look good. As an alternative, I've used Superseal connectors before, most recently to wire in spotlights. They seem to keep the water out just fine. Instructional video here.

Then copy a whole C:\Program Files (x86)\Garmin directory from a Windows x64 machine into ~/.garmin/drive_c/Program\ Files/Garmin. You obviously need a functioning windows version of basecamp to do this. I run Windows and Linux on two separate hard drives on the machine I did this on so it was ...

I'll follow that up. In the meantime I've given up trying to install Basecamp via Wine. I keep meeting different errors which the various forums seem unable to solve. And I've decided not to install Windows in a VM. Microsoft is just going too far in the wrong direction for my liking! So MRA will do ...

I was also nervous about doing the update over WiFi in case it failed, or corrupted the map. But finally I decided to try it, despite the very pessimistic 3-hour time estimate. WiFi actually took only about 25 minutes and the XT is working fine. Whew! More fun with Garmin.

Thanks for that ...

Thanks Mzokk. I managed to dual boot on the laptop, but decided to go full Linux to give that a proper try. I was pleased with the result, but in retrospect I should have kept it dual booting. I tried to dual boot on my PC, but kept running foul of partitioning. In the end Windows was becoming ...

I've finally taken the plunge and ditched Microsoft. My PC and laptop now run very nicely, and quicker, on Linux Mint. I'm prepared to do all my routing on MyRouteApp, and do XT upgrades directly via WiFi. However, it seems possible to run the above two Garmin programs either through Wine or in a ...

And JaVaWa's GMTK did the job in less than a minute! Now to move the other surplus files.

I'd forgotten about that. I'll have a look.
