Previously had this issue with my Nav V and also on my new Garmin XT2. I've built up a huge number of routes over the years (some mine/some others I've used from the web and modified to suit etc). When exporting (either individually or a large file transfer some route names change when they appear on the device (or Tread app as I'm now using) I can go in and change it on that app but that takes a huge amount of time. As I said it's not every route - is there something embedded that the navigator picks up?
Naming convention as follows:- 001 Oban to Glencoe and Crieff loop (289m-7hr) I might get SD Oban to Glencoe and Crieff and that's it. Others will not have SD at the start etc.
Any ideas on how to fix as I need to transfer many files to my new device and I'm not wanting to rename multiple different routes manually.
