Edge 1030 Loss of turn by turn navigation functionality since firmware 8.0.0 update

I created a route on RideWithGPS this afternoon, loaded as a .fit file using the iQ RWGPS app,

The device is a new'ish 1030 on OS 8.  TBT worked just fine.

Big thank you to everyone who's chipped in on this. I'm happy to report that I tested a bikemap.net gpx file just now and it worked fine. The difference now is I've turned "Lock on road" OFF. Lock on road must be used by the 1030 when it converts the gpx files it finds in the New Files folder to fit files. With "Lock on Road turned on the generated fit file is somehow corrupted and TBT functionality is lost (that's my guess anyway). So pleased to be able to use all those bikemap.net gpx files again. Cheers

The "lock on road" has nothing to do with it either. "Lock on road" has nothing to do with routing: it's just used to adjust how the location cursor is displayed.

The routing always follows roads/paths regardless (that's how it works!).

It works the same way with that enabled.

The bikemap GPX files are like every other GPX file. They are the same sort of GPX file RWGPS produces.

There's no magic in the file (it's text, which means you can verify that).

"I created a route on RideWithGPS this afternoon, loaded as a .fit file using the iQ RWGPS app,"

It's not a problem. If it was, you'd be hearing more noise about it.

The RWGPS app isn't doing anything different than copying the FIT file to \Garmin\NewFiles.

I'm not sure what issues Tourer is having but no one else appear to be having the same problem.

The bikemap GPX files aren't any different than the GPX files produced by RWGPS. Both work fine,

Nevertheless, TBT didn't work using the same gpx file with "Lock on road" ON, yet it works with "Lock on road" Off.

It seems your issues might be particular to your unit.

If it was wide spread, there would have been other reports.

There have been reports of odd things with "lock on road" but not your issue.

I don't see the point of "lock on road" anyway.

The route calculation is already using roads (it has to; it's the only way it can work).

=========================

Providing answers to the questions I asked might have let people understand what exactly your problem was.

Do you get the "Calculating %" message when you load the course?

If so, do you see a list of turns when you click on the text at the top of the map?

Yes, I got the %age calculating when TBT was not working. There was a track to follow on the map, but no text prompts popped up as I rode. No audible prompts of impending turnings either. Having checked the 1030 today using gpx files generated on bikemap.net, it does give a text list of turnings at the top of the screen, whether lock on road is turned on or off. I'm at a loss to explain why I lost the TBT functionality, but it was a real issue for me. I experienced no problems before the firmware update, so I assumed that had something to do with it, but maybe that was a red herring

Related to this is my 1000 stopped doing TBT pop up at some point about an update ago.  Thinking it was the unit (as well as assorted BT problems) I replaced with a 1030.  

THAT unit, on OS 7.5 had the same TBT issues.  It (and the 1000) would do TBT, but was taking about 45 seconds to figure out a turn had been completed and restore to a data screen.  I could see on the map page that the unit had my position correct but the TBT cues were not updating and I would miss turns. This was with either RWGPS .fit files or Garmin Connect courses (same thing essentially).  The issue mysteriously went away before the OS8 update, with TBT working on OS8.  I've not recently tested the 1000.

I'm not denying that it was a real issue for you. 

That extra info helps. What you are describing sounds sort-of like a problem other people experienced.

You should say "turn guidance" (that's Garmin's term for it). TBT could mean "turn guidance" or it could mean "course points" (which is a separate thing that provides turn information).

I had an issue where the "turn guidance" wouldn't progress (the device acted like you weren't moving). The fix for that was to reset the device (hold the off button until the device shut down and turn it on again). It was a weird problem because there wasn't any apparent pattern,it didn't always happen, and people on the same ride with the same route didn't have the problem.

Other people had the same issue and that fix worked for them as well (it was reported in this forum multiple times).

I haven't seen this issue since updating to 8 (but it just might not have happened yet).

So, if you have the issue again, try resetting the device.

======================

There some chance that it's related to "lock on road" but, based on long-experience with these devices, I think it's unlikely.

It is much less likely that it's the file IF you see a track AND the track more-or-less follows the roads on the map.

If the device creates the list of turns, then it certainly isn't the file (since it's done with the file at that point).
