Navigation » Planned route problems

Hi Guys,
I don’t know if this problem has already been dealt with (working out what search words to use made it difficult to search the forums).
I’ve had the same problem twice recently with my nav 6.

I’ve planned the route, but for some reason, part way through the ride the damn satnav tries to take me back to the start of the route again.
I do appreciate that on both occasions the route out, crossed the inbound section at one place, but it was planned as one circuit as opposed to just A to B.
Any idea how to tell the Satnav to pick up the route from here and continue to the next waypoint?
I hope my explanation makes sense.
Kind regards
Mark

Oh, the joys of GPS.

I’m happy to say I’m beating Garmin more times than it beats me these days.

Yesterday an 11 point, 290 mile route ran perfectly. Auto recalc deliberately turned off so that my route couldn’t be corrupted.

It’s a game.

Thanks Wessie,
I created the routes in Basecamp then imported them.
I'll create within the satnav next time and see how that goes.
I get your point about exit side of junctions and have been doing that.

I didn't know I could turn off auto recalculate route, so that's going to be a big help.
Thanks very much.

I’d have to see your routing to see what the problem is. I’ve never had an issue with being jumped back to the start of the route. I do know, in the past, that sometimes a GPS asked if I wanted to start from the start of the route, which would then navigate me to the start of the route, but never during a running route. This question was asked when starting a route not near the starting point.

I had a route where the GPS kept trying to reroute off road, but that was because the waypoints didn’t line up with the map database, so it was thinking I was trying to go to a point 100+ feet off the mountain road. In that case I used Garmin MapSource. From that point forward, I had to use Garmin Basecamp. The map data was correct, but how MapSource did the routing was different from Basecamp...which might have caused the issue.

It does sometimes screw up.
If you're using Basecamp check you have exactly the same map data and routing options in the device.

Once you have the route created, zoom right in (I mean right in) and check your way point isn't on the wrong side of the street as this will detour you back so you hit it.

Also as Wessie said, turn off auto recalculation, if you go off track or don't agree with the nav, just zoom out on the Wunderwheel and check you are still heading in the right direction until you join back up with your route.

I tend to use as few hard way points as I can, start/ stop and any planned stops for fuel, coffee etc and use shaping points to pull the route to the roads I want to use.

Thanks Guys, I appreciate the advice.

I suspect your problem is to do with alerting/non alerting waypoints. When you plan a route its important to plan with say 10 waypoints. Also never place your waypoints on a junction, endeavour to place them before or after a junction. If you miss an alerting waypoint the GPS will keep returning you that destination. Too few waypoints can result in your planned route being abandoned and the shortest route to your destination is unilaterally adopted by the GPS. I know this sounds crazy but there is method in this apparent madness. Rather than explain the intricacies of Basecamp look up Moto Guru on YouTube.

I stumbled across this excellent tutor on YouTube, he goes by the name of Moto Guru or Joseph Byrne. He has produced a series of videos that cover all of the essential facets of route planning with Garmin Basecamp. He has even produced versions for both Mac and Windows equipped computers. I can't sing his praises loudly enough, the videos are clear and easy to understand. It's well worth a wet afternoons study. He is in my opinion, the best tutor I've come across. Remember practice makes perfect, plan some short routes and then ride them. Good luck.

Hi all, you can have more than 10 waypoints. I've created a route with too many way points and vias that upon import, my Nav6 would split it into two routes, but it's fine.

I, like others above, suspect the issue is in the route calculation or recalculation settings. i.e. what happens if you go off route. It could also be not enough way points or via points, as Riggo mentioned.

One thing to check: create in base camp, upload to GPS, and then before your ride, preview the ride and follow the route on the NavX, to ensure it's correct. if it's not, go back to Basecamp and revise, reupload and review. continue until accurate.

It'll be a pain the first few times, but then you'll know what kind of waypoints/vias you need to get what you want.

FWIW, on a 300-400 mi day, I will have 30-50 waypoints and vias. I have set the waypoints to 'announce' and the via's not to 'announce.'

Another critical factor in addition to same maps, is same calculation method. I tend to go with "fastest." but you need to make sure that both Nav unit and Basecamp are both using the same (shortest, fastest, curvy) routing setting.
