Garmin XT2 - losing my mind!

[Julian Roberts 0 0]

I know lots has been posted about this subject but I’m hoping someone might be able to stop me going any more crazy.

In short, I have been having real issues with translating MRA routes into the route on a Garmin XT2.

I have created routes in MRA using HERE maps with plenty of shaping points. I have copied them across from my iMac directly. The route in question is 233 km. MRA says the route will take 3:30. The Garmin calculates it as nearly. 4:30. It looks like the same route on the route preview. It’s not the first time I have had issues with this. Earlier today the Garmin just made up its own route. When I realised that something was amiss and check the route on MRA we were some 15km off the route and the Garmin had just given me this route.

Am I doing something totally dumb or have I potentially got a dodgy XT2.

@Julian-Roberts-0-0 HI! I am not sure if this will help, but please check the Navigation preferences setting on your Garmin. Every time you call a route for navigation on the Garmin, you will notice that it says "Calculating Route". It means that it calculates it based on the Nav preferences set on Garmin AT THE MOMENT.
Also, if you have live traffic data it may calculate differently based on traffic conditions.
When I was using Garmin XT (now coimpletely switched to the MRA NAV App), I had an App called Garmin Drive installed on my phone. After Bluetooth connection is made between the phone and Garmin (only do it once), to transfer a route to the Garmin, I would pull up the route on the MRA Nav app, slide the bottom bar to the left to uncover a symbol of underlined down pointing arrow (download), select the format (usually GPX 1.1), hit Yellow Download button, then select Export, then Share and when asked which App to use to Share via, I would select Garmin Drive. And Voila!
The Route is wirelessly transfered to my Garmin XT.
I am positive that XT2 has the similar functionality, though slightly different and using Thread instead of Garmin Drive. Once you master that procedure, you will never need a computer again.

Drive App is only working with XT1. XT2 and XT3 have to deal with Tread.
@julian-roberts-0-0 try to export gpx1.2 and put the GPX-file in the /GPX folder. That should work. Keep your recalculation off.

I'm quite sure it would not be a solution, because in the transmit procedure XT calculates too. And this can't be switched of. The only solution is: to enter enough route points...
