It's my understanding that the 800 resolved the cable problems people were having with earlier models, e.g. with a 700, you need a special cable.

Please try it and report back. I don't think that this will help. I'm not talking about situations where the GPS computes the wrong route and you mistakenly follow it. I'm talking about situations where the GPS has computed the correct route, but you forget that the cue sheet says there's a turn coming and don't notice the GPS telling you to turn, e.g. because you're talking with someone or dealing with traffic. Once you've missed your turn, an eTrex 30 just quietly recalculates the route without telling you. With an HCx, set to not auto-recalculate, it beeps and pops up an alert message to tell you you are off course and leaves that message up for maybe 30 seconds. After the message disappears, nothing further happens. You ride further from your turn, and away from the purple line. Eventually you look down at your GPS and notice you are no longer on the purple line, and the "distance to next turn" is going up, not down. That's how you know you're off course, so then you turn around and ride back to where you missed your turn.

CFB, missed this one previously. It sounds like you haven't bought Garmin maps on memory cards, since you've got maps on multiple cards. Which maps do you use, and how do you get them onto the cards?

The problem is exclusively with the 500.

I actually tested my 500 and 810. The 810 can run when attached to power, the 500 does not. The cable that ships with Garmin units is a standard micro USB. The issue is strictly with the pinouts on the 500.

And here's the experience of a guy who did RAW/RAAM, and saw the same issues with just the 500: https://forums.garmin.com/showthread...harger&p=95222

Fortunately, it is now fairly easy to work around it, if you're willing to buy the modified cable from Gomadic. So, you do have the option of using a battery pack if you like.

Heh... I'm writing here from an abundance of trial and error. Yes we're not talking about the same thing. I'm saying that without precise use of shaping points, the eTrex 20 will route you anywhere based on its routing algorithm, which involves a lot of calculus and may or may not reflect what you programmed into Basecamp. It particularly thinks that MUP's are toxic or something. Basically unpredictible. Then there's the limit on how many shaping points the unit can handle, where it refuses to offer *any* route. I struggled with the issues long enough to throw in the towel and use tracks for all my rides. But as you mentioned, if the Garmin designers had kept the option to disable autorouting on the newer model, the problem would not exist.

You are correct. Waste of money, and PITA IMO. I use OSM maps. I used this website to start with:
OSM Map On Garmin/Download - OpenStreetMap Wiki
For the US I think I used osmmaps.com
or maybe it was VeloMap.org -Roadbike ? Bicycle ? Maps based on Openstreetmap Windows/Linux ? VeloMap Map Downloads
For Europe I use openmtbmap.org

It's a little complicated, but not all that bad. The maps can be so huge as to slow down processing. I select an area that gives me a map size of under 4GB.

A comprehensive worldwide source is Free worldwide Garmin maps from OpenStreetMap

Don't know how other units work but I plug mine into the computer and just copy the downloaded .img files into the maps folder on the unit.

If MUP means a bike trail, the problem there is that those are not on the map that Garmin leases from Navteq. I would think that if the trail is on an open-source map that the GPS would just treat it like a road and route on it.

Garmin has a 50-viapoint limit on routes. But that's almost never a binding constraint if you make routes that go from control to control. Out of hundreds of rides that I have made a GPS file for, there are only a couple where there are so many turns between controls that I run out of viapoints.

The eTrex 20 works like the 30. Saturday I missed a turn and it not only recalculated the route but also routed me down a dead end road. I called Garmin Tech Support and asked if auto-recalculate could be turned off. He said no but to put in a suggestion on the web site under contact us, have an idea. He said the more people that put in a suggestion the more likely it will be fixed.

Yeah the reasonable expectation would be that the unit would cooperate with viapoints placed on cycling paths.

But it doesn't, and neither does BaseCamp. At least with the OSM maps that I use. So I'd be curious to hear from other eTrex 20/30-BaseCamp users about this. There are long MUP's (Multi-Use-Paths) I ride, and the only way to make it route on them is to put viapoints between every intersection. Then there is the limit on viapoints which presents a different set of problems.

I even tried creating a walking route connecting two ends of a MUP. BaseCamp used the sections of trail at each end but routed most of it on River Road and some of it even on the interstate. I'm going to put in the suggestion as mentioned above, but in the meantime working with tracks instead of routes seems to be the best solution for the newer eTrex units.

It's funny how everyone today is hooked on technology for navigation. Get a map and chart out your route. It's much more fun!

I think the fact that so many of us are hooked on GPS technology is a good indication that we have more fun riding with GPS than with a printed map. I have done both and far prefer the GPS. It's good to hear that some people stick with the traditional ways. (Different strokes for different folks. Variety is the spice of life. And all those sorts of aphorisms...) You may have more fun with printed maps, but I'm sticking with my Garmin...or in a pinch, even my iPhone.

I've used the cable that came with the 800 with an external battery charger (something that works with iPhones) with no problems. From my understanding, a firmware-release changed (fixed) the problematic behavior.

That is an easy-to-use source. I don't find that the "bicycle" specific versions work very well in the US.

Ah, good as I've used an external battery pack with my 510 and reg USB cable, and had zero issues. I thought maybe I was missing something, lol.
