Hans, Reinhard et al,
After reading your replies I thought I would go on a test ride again.
This time a 70 mile circular route comprising of 17 waypoints. I saved 3 copies in gpx 1.1 Beta track, route POI format, a gpx track + POI and finally the old gpx 1.0 track, route, POI. The route made using the HERE setup.
The general idea was to follow the route (of course) but periodically go ‘off route’ or stop and switch the Garmin off plus ask the unit for a petrol station en-route.
Started off with the Beta file. All was going well, I went off route and after a re-calc it did indeed point me back on route towards a waypoint created within MRA. I ignored this, went another way which I knew re-joined the route further along. Again the Garmin steered me along the route but this time it was leading to a waypoint further away from the one I knew I was coming to. I pulled over and stopped the route altogether. I then loaded the gpx 1.0. I was off route and asked for the ‘nearest point’ to re-join. It successfully directed me ‘forward’ along the route and not further back to a known waypoint.
Again I continued along all going well, paused and flipped back to the Beta file. Set off again but later on searched for a known garage en-route. On approaching the small town a heading gave the chosen garage name and distance ahead. As it was by the roadside I just drove straight past it. I ignored the prompts to u-turn back to the garage and after 100M the Garmin ignored the garage stop and continued. I then stopped for 30 minutes before re-starting. On heading back home after 15 miles it was trying to lead me back home via another road? Strange, I ignored this and sure enough I continued on the chosen route only to find 10 miles later the Garmin was trying to take me off route again. I stopped before the Garmin ‘detour and stopped the route. I loaded the gpx 1.0 files and sure enough it was heading me back on my chosen route.
So, I realise Hans/Reinhard that this is a bit ‘hit & miss’ and ideally 2 bikes each with the different formats would be better than me stopping, starting and changing formats. I agree the Beta format does not have the waypoint flags and therefore there may be no limit to Via or Shape points when imported into the Garmin. I am allowed 29 waypoints in the 1.0 format.
The practise of importing a ‘track’ and letting the Garmin convert to ‘route’ does not fill me with confidence, although it may be perfect! I also realise that shaping routes and adding points via the Garmin is something I am not used to doing.
I am I guess not that proficient in using Sat Navs and therefore just want something simple that just works. I want a unit or file format that takes me from A to G and if I go off route at D it will not guide me towards B or C but point me in the direction of E and F. I don’t want to find myself in the middle of nowhere wrestling with a unit that does not want to go where I want it to go.
After further practise Hans and speaking to, or reading about, other users methods or procedures then I may see the benefits of using the Beta format.
As the famous Eric Morecambe (British comedian) once said whilst sat at a piano and getting a telling off from Andre Previn, “I’m playing all the right notes, but not necessarily in the right order?”.
