Spent all night playing with Sport Tracks and adding different plugins, how accurate is the power plugin? I am not really sure what to expect from it, would it be an ok tool at getting me in the ballpark of what power I am putting out?

luv2climb

Here is a power calculator that you can sanity check it against:

https://www.saris.com/powercalculators.aspx

I compared it to actual data from my PT for my last two rides and it comes in within 1%. Note that the Saris link above shows your power including when you are not pedaling. I am not sure what the Sport Tracks plug in shows. If it drops out the 0's then the power figure it shows will be higher.

Bug in Mapsource version 6.15.3

I've frequently setup loop routes that start and end at the same waypoint. There was no problem in previous version. Version 6.15.3 crashes every time you try to calculate a route that goes through the same waypoint more than once.

Course questions

I have been trying to use the course function on my 705 on long (100 mi.+) rides but I keep having to turn it off due to off course error messages and bad turn directions

If you have a course loaded, is there a way to get it to start navigating forward on the course at a point other than the start?

Is there a way to get it to skip course points if you depart from the course and want to resume at a later point?

Thanks

I've found that the Garmin will pick up automatically in the middle of the course, if you don't get too far off course and its set to automatically re-calculate. Are you getting the course error messages because you actually get off course? Virtually every course "error" I encounter is because I built a route that did not have the turns in it that I throught it did. I now load the course, turn off the GPS mode and run through all the turns on the Garmin ahead of time to make sure it has the turns in it which I expected. I always find at least one error on new courses I have built. I also found that using anything but mapsource to build the course was a sure way to have errors.

Thanks, I'll try checking the course in advance. So when you leave the course does it constantly update to direct you back to the closest point on the track?

One other area seems to cause it to get confused is bike trails, which we have a lot of here. When in recalc mode it wants you to get on an auto route that can be miles out of the way.

luv2climb

Are you sure you are talking about a course? Courses will NEVER go throught a recalculation, they are fixed to whatever path you set them on. A route on the other hand will recalcualate EVERY time you deviate from it. With a course you will simply get a warning that you are off course. In addition a route may have troubles if you start in the middle of it.

cheg

Don't you get directions on how to return to the course as well as warnings? It must be calculating something.

luv2climb

Course's will only give turn warnings if you place them in the file. It will only calculate when you initially start the course, it will not calculate or recalculate again. If you have left the course and find your way back to it you will get a notice that says course found, updating virtual partner.

When menu path are you following when you launch the course on your Edge?

What is the file extension on it? TCX is a course, GPX is a route.

cheg

OK, thanks, now I know something about how they work. I've been downloading them directly from the internet to the garmin from bikeroutetoaster and expecting more turn warnings. I thought they were auto-generated. They are TCX files.

The menu path I have been using is Menu > Training > Courses > Do Course

The status page always gives a distance to course but I never knew if that was to the closest point or to a course point. Generally the turn indications are not very descriptive, just "Turn Left", "Turn Right" and a distance. I wanted to know if I could tell the GPS to skip ahead to a later point in the course.

luv2climb

The distance to course appears when you leave the course. It is the straight line distance to the closest part of the course, not a specific point. The turn indicators can be very sparse. You can always open the course in Garmin Training Center and add more if you like. There is not way to tell it to skip ahead with courses.

I received note from Garmin tech support acknowedging this bug. They said there were other known issues with version 6.15.3 and recommended I revert to 6.13.7 until a new version is released. I did and the problem I was having (re-using waypoint on a route) is not present in 6.13.7.

Newbie needs help.

I recently purchased an Edge 705 with the hopes of using it for some light touring this year. I was initially using bikeroutetoaster to generate the routes and they worked fine. However, I noticed that the Garmin maps were much more current. I traded in the SD version for the DVD version. When I built a route using mapsource, I noticed that the Edge would not route me the same as shown. As a test, I generated the same route with bikeroutetoaster and mapsource and uploaded them as gpx files. The bikeroutetoaster route worked fine, the mapsource route did not. I uploaded the mapsource gpx file into brt and see that the route is the same. Any hints in where I need to start?

wrobertdavis

I've had just the opposite experience - mapsource is much more reliable than bikeroutetoaster. Checking the mapsource route on brt is not valid because they use different maps. There are subtle differences. When you say "it doesn't work", what do you mean? Can you be more specific? If you're willing to mail me your two gpx files, I'd be happy to have a look and see if I can help you find the problem. Let me know and I'll send you my email address through private message on this forum.

Thanks for the quick response. I created a simple route for a test. I make a single right hand turn onto a side street. Travel two blocks and make a left turn to return to the original road. Bike route toaster follows the route that I create. Mapsource will continue down the original road.

wrobertdavis

Are you saying this is what happens when you load them into the Garmin? I've never had the Garmin take a different route than mapsource did. What are the route settings in mapsource and what are they in your garmin?

Bob

sbuch53

This only occurs when I upload to the Garmin and Navigate via the route. If I look at the map on the GPS it shows the same route that I created in Mapsource. I will PM you with my email address and can send you the history of what I have tried.

Hello, I have a question for setting up the wheel size on my 705. Is it better to choose the specific size or choose the automatic setting? How accurate is each? Thanks!

wrobertdavis

I've been happy with the automatic option. I noticed the wheel diameter chosen when I got the garmin was slightly smaller than the chart size, which would be consistent that my tired had 1800 miles on it. I've noticed the automaticall selected size has changed as the tire wears. I now have 3100 miles on the tire. Intuitively, the automatic option seems like it could be more accurate, but I have not run any detailed analysis.

Can anyone tell me if it's possible or of any value to put a higher capacity memory card in this thing? Garmin suggest a max 1Gb but up to 8G are readily available. Wonder if it might be useful for tours and such when It'll be weeks between downloads. With two bikes and one motorcycle this puppy will see some miles.

Also, has anyone worked out a safety leash or augmented the mount in some fashion to reduce the odds of it flying off as many have reported?

paulrad9

I thought 2 gigs was max

No leash, but how about two zip ties?

luv2climb

As mentioned above the max that you can use is 2gb. I have heard rumors that placing a larger card in will actually prevent the Edge from operating. Provided you have loaded all your maps on a SD card the internal storage should be more than enough to hold the history files for two weeks or more. In addition, there is no way when you in the field to have the Edge copy the history files to the SD card. It will only save them to internal memory.

I curruntly have mine set to one second recording and am using a power tap (both causing files sizes to more than double). The Edge has over 45 days of history still on it that has not been deleted and is functioning fine. The motorcycle use should not impact the memory file unless you are also recording the data while you are riding the motorcycle.



Mine has never flown off. I have a year of use on the 705 and prior to that I have 3 years on a 305. Neither of them came off. I will admit that I have broken two mounts. One becuase I was over zealous and had the zip ties WAY TOO TIGHT! The other time I was a brute and broke the release tab off. However, both mounts were still usable after the breaks and the Edge would not fly off. If you are very worried you can place a zip tie around the top of the Edge and your stem (assumes you are stem mounted) and this will keep it in the mount.

I put in an 8 gig and it wouldn't even start

kenshinvt

I haven't seen "many reports" of it flying off. The mount is very secure.

The only issue I have with the mount is a bit "sticky" for the first 10-20 clip-ins. That is to say it's difficult to get the release to work smoothly. After that point it seems to bend into place and it's easy to clip in and out.

CastIron

Thanx folks. There will be more. I just got the map CD in my hot little hands.
