I typed in test as a name. When I have multiple maps on my GPS SD card, the name I type is the name of the map if my memory is correct. (I have not done this for months, I might have that wrong.) I click extract. Then it sends me an e-mail telling me when my map is ready. When it is, I put the IMG file onto my GPS. I think this website is limited to half a GB per map, I might have too much area on that map in the example, if that happens, make it a bit smaller.

They have other formats, I have not played too much with various formats, I found I liked this format for biking so that is what I have used for years.

Since the GPS I use takes AA batteries and I saw some Etrex models do too, you can either buy disposable or NiMH or Li Ion rechargeable. I have not bought disposable AA or AAA for over a decade and a half. I use Ladda 2450 NiMH rechargable from Ikea or if not near an Ikea, Eneloop batteries. I mentioned in my previous post I can charge them in my GPS, but I think you can't with the Etrex.

I mentioned you can also buy AA or AAA that are Lithium Ion. I recently bought some of them too, have not tried them on a bike yet. They put out a constant 1.5v until they are empty. So, they very suddenly will be empty and you need to swap batteries. Thus, they might not be the best choice for bike touring as you may look at your GPS and suddenly realize it is off, time to pull over and swap batteries, which could be an inconvenient time. But if you want to try those, they can be charged by plugging a USB-C or Micro USB cable into the battery. You might find some of these on amazon if you are interested. I am using these at home on some electronics that work best at 1.5v, like my kitchen scale, etc.

Over the years I have bought three or four different AA/AAA chargers that run on a USB cable. The Powerchimp I used on my 2019 tour is below:

https://cimg5.ibsrv.net/gimg/bikefor...f18fc868e9.jpg

In the above example, three batteries are still charging, one is full. Same device below not plugged in. I am charging AAA in this example, can also charge AA.

https://cimg6.ibsrv.net/gimg/bikefor...c0c2c29c0d.jpg

Or a different AA charger. Photo below has the Eneloop chargers that can charge two AA and a camera batter charger, not sure if these Eneloop chargers are still made, photo is nine years old so the chargers are older than that. I was charging up two sets of batteries from a wall charger in Iceland.

I have a dynohub on my front wheel. I use a Cycle2Charge to convert my electric output from that to USB. I put that power into a powerbank when I am rolling with my lights off. (My taillight flasher is battery powered, not powered from dynohub.)

I suspect you can't buy Cycle2Charge chargers any more, they are made and shipped from Germany and I think nobody in Germany is shipping stuff to USA due to the tariff uncertainty. That said, I used to use a Sinewave Revolution, they are still available because that company is in USA. And there are several other options to convert dyhohub output to USB power.

I use a Voltaic powerbank, I can charge it and discharge it simultaneously. In other words, I can plug my dynohub charger in to charge it while I am using the powerbank to charge other devices like my phone.

But kayaking or canoeing or backpacking, I bring a lot of batteries, do not try to charge them during a trip. I brought a solar panel on one trip but decided that the batteries were lighter than the panel was for the amount of power that I actually got out of the panel.

On my last tour a year ago, described here, there is a section on electrics. Describes some of this in more detail.

For other activities I usually use topo maps from this site:
https://www.gmaptool.eu/en/content/u...-topo-routable

Your last comment, your Son did not provide enough power, what did you put the power from the Son into?

I am somewhat obsessive to make sure I am not wasting power. When the visibility is good enough to have my dyno powered lights off, I am charging my powerbank (Voltaic). But, dynohub output is only giving me roughly 2 watts on average into my power bank when you factor in hills, photo stops along the way, etc. On a hilly segment, cut that in half. And my taillight flashers are powered by AAA. Thus, most of the time my hub is only used to charge batteries.

My 2019 tour, I did not even put dyno powered lights on my bike, the dynohub was only used to charge batteries. If I needed a headlamp on my bike, I had a cheap light that is powered by USB cable that I could plug into my powerbank, but I never needed that light.

Since I am setup for charging AA and AAA batteries, my headlamp (for my head) is powered by AA too.

I bought my first GPS over two decades ago for kayaking. If I was paddlng towards an island and the fog came in, I did not want to accidently paddle past the island. The GPS I bought did not have a built in map, but I could enter waypoints with Lat and Long locations, so I put all the campsites I might want to go to into the GPS. Then I felt safe paddling in fog towards a campsite. Example below, this is on Lake Superior:

https://cimg1.ibsrv.net/gimg/bikefor...adcf03751b.jpg

You do not see the GPS in the photo, that was sitting on top of m spray skirt, so I could look down at it and see where I am on the map. Photo below, that is exactly where I wanted to be when I got close enough to see land. I wanted to pass this island on my left.

Got it. I only sea kayak, not white water. And in white water, you don't really need a GPS because your only choice is to go downstream.

I suppose a GPS could be used to tell you how far you are from the next rapids, but in that case you could put it away in your PFD pocket before you get into the rapids.

I have a bit too much stuff on the outside of the boat to try white water.

That's a really good idea ! I often diverge from my planned route, mostly to find a quiet wild camp site. Which is your preferred app to split gpx ?
Thx

Biking dedicated GPS are organically designed to make it easy to create a route or multiple routes on Garmin or third party and get those routes onto the device very easily. If you need to transfer .gpx files to a hiking model, which I don't know how well that works and is a bit more work involved every day. My preference is an Edge with good battery life like a 1040. OTOH, I have followed a couple doing a cross USA as well as cross France who used a generic Android phone and Kamoots. The phone had an external battery for supplemental power. This seemed to work very well for them, so it's a good option it seems.

There is a reason why there are cycling-specific GPS navigation computers, and yes, you should feel uncomfortable with your choice. It is going against what a vast majority of touring cyclists are using. Onboard cycling-specific navigation, built in worldwide maps, searchable services such as accommodation, bike shops, etc., simple wireless route transfer, popularity routing which takes other users into account, live tracking, incident monitoring, live weather radar, etc. The only people advocating for the use of Etrex are those who have never used a current, full-featured Edge device.

If the one you have works for you, I would stick with it. When you said you wanted to replace the battery, I immediately assumed you meant frequent replacement, like AA. I did not realize you mean after several years.

Not sure why you need to replace the screen. I have replaced a screen on a 64ST that I bought used on Ebay, followed instructions I saw on a couple youtube videos, the screen cost about $20 for an aftermarket one, but that was before tariffs. I could see in the photos before I bought the GPS that I would need a new screen.

I put clear packing tape on my GPS screens when new, replace the tape when it gets scrapped up enough.

Now you can buy powerbanks that hold a lot of watt hours. And a high charger USB-C charger that can charge them up pretty fast. If what you have burns through battery too fast, maybe you need a better power bank(s).

Looks interesting but I haven't used it. For day rides, I'm using my Garmin watch these days because it tracks HR. It integrates with Strava, which I'm kind of vested in a this point because of all the data that I have there. On multiday trips, I'm not tracking things like HR so I'm using OsmAnd on my phone

Not all kayaking is down a river. I use my Edge 1040 on lakes in the Adirondacks when I need to know my position and the location of rivers or bays I want to explore. GPS tells me that. Likewise in the bays where I live, countless islands and stuff, I need to see my position to explore canals and tidal inlets.

Hi there,
My latest buy was a Garmin Explore 820. Honestly I hate it : the display is really small, the accuracy really perfectible. And the unit is totally glued : it's almost impossible to replace the battery or the screen.
I'm looking for an alternative Touring self serviceable GPS : is there something available somewhere reliable enough ?
I just need a good mapping and a reliable itinerary planner, possibly with a correct battery.

I'm ageing, so do my bike : it's a Santos TravelMaster 2.8 with Magura rim brakes, a Rohloff with an outdated Gates belt drive. The wheels are a bit too thin, anyway, I'm still happy with it. Changing for something more "modern" is out of question, money wise at 65. Plus my wife would be horrified to see another new bike...
