Yeah, that would work but I meant something different. Edit the course and set its colour to bright green or something. Then set it to "Always Display". Then you can follow the green line on your map without the Garmin trying to route you somewhere wrong and presumably uses less processing power as it's not calculating the course over its installed maps. You don't get stuff like Distance to Destination but it's better than the Garmin turning a 400k audax into a 600k because of its fucking stupid routing (which happened to me on the weekend and was why I stopped the Follow Course option in the first place, now I think about it).
So you export a GPX course and navigate with it but with TBT turned off?
My GPX files give me TBT on 800 and 1000 if I have it enabled, which I usually do. The difference with the TCX is it pops up little notes for every cuesheet instruction as well ("Turn left toward Middlegreen Rd" or some shit).
