So, back to my original question, does anyone have comments regarding the newer version of the Zumo XT using routes developed with MRA?
I was not aware that there is now an XT3 model available.
Hey Don. I'm a long-time user of the Zumo XT executing routes developed with MRA Routeplanner. I'm a huge fan of Routeplanner, even though I still use Basecamp (BC) for very occasional special cases.
The Zumo XT3 has been out for about 6-months. The only reason I bought it was because I misplaced my XT and needed an immediate replacement. I've since found that XT but I'm so impressed with the XT3 that it's the only model I'll use moving forward.
Now to your question -- The XT3 is perfectly compatible with routes developed in MRA Routeplanner. I've only had my XT3 for a couple of months, but I developed several routes, many longer and complex, without any execution issues. The updated 3D Maps going from the XT to the XT3 are eye-popping and make the navigation experience even more compelling.
Be aware that the XT2/XT3 devices are designed to make greater use of the Garmin Explore DB. This is Garmin's attempt to create a HW ecosystem similar to what Apple has done across their devices. What this means is that whatever routes you create are kept in their storage Cloud, where different pieces of your routes (Collections) are available for use in other Garmin devices you might own. It sounds good in concept, but there are high chances that your routes will be manipulated in ways you don't intend. It's been a serious problem that has been the subject of many social media forums. Many users have thrown their hands up out of frustration and given up Garmin altogether. The answer is to NOT enable external storage (Explore DB) when you install the Tread app, which is the XT Drive app equivalent. The downside is that you'll have to copy your GPX files manually to the XT2/XT3 device. The advantage is that your route will in no way be manipulated/altered. I've used the manual method forever, so I personally didn't look at it as a downside at all.
BTW, if you haven't tried the MRA GPX 1.2 download format, give it a shot. There is a great topic explaining how it works in the Export Assistance Forum:

Good luck with whatever you decide.
