Noob on Surface Pro 2017
I ran Gaiagps on my Droid but needed a bigger screen for on the road use. The Surface is the only system I could find that was capable of an external GPS via USB plus external video input from my camera system.

I primarily purchased this to develop a (hopefully) one display system for my on and off road travels. Last year I used my smartphone which left me hanging a number of times.

So my system will use a GlobalSat BU-353-S4 USB receiver.

As far as I can tell Gaia is not available for Win10 PC use yet.
I will need a software that is not wifi or data based since I learned last year that I can't always count on reception/connection.

I have looked at the Land software and it would appear that in order to use my external GPS I have to purchase the Premium version.

What are my options? Searching through the posts, many of them are several years old and technology has changed quite a bit since suggestions were made.

I would like to test my system out this June on a 10000 mi combination on and off road trip.

GpsDirect by TurboIRC can convert the Com port NMEA data produced by your BU-353 for use with any Windows 10 mapping program. You might consider the Win 10 built in Maps application but whether it would meet your off-road needs is another story.

I looked in an area of the Crowsnest Pass that we started riding and camping in back in the 70s. Some of the main forestry roads in there are sizable and have been around for decades. I looked in Windows 10 Maps and on Google maps.

My first impression of both is that the contrast sucks! Their smaller highways and secondary roads are white with a faint outline against a nearly white background. Really quite awful.

Second, almost none of the primary forestry service roads are shown on either one.

All of the forestry roads I'm familiar with and some of the regularly used logging roads are shown on my Garmin City Navigator North America maps. And those maps display with excellent contrast in either Mapsource or Basecamp. Unfortunately neither of those do real time navigation.

Open Map Chest has excellent visibility and has even more offroad content than the Garmin maps. Like the Garmin maps, it displays in Mapsource and Basecamp. Unlike the Garmin product, it's free open source. Unfortunately I don't know if there are any Windows navigation apps that will use either the Garmin maps or Open Map Chest.

It looks like MapFactor GPS Navigation app from the Microsoft Store will use maps from Open Street Map (different from Open Map Chest but similarly free and pretty good for some of the oiff road content).

If nothing else, it's a way to do some testing. I suspect it either has ads or will require money to unlock features. After all, nothing is ever really "free".

I also expect it will need the GPSDirect app that Terry mentioned.

If Garmin maps are a viable option, how about going "old school' with Garmin nRoute! We know it is free if a little non-touch friendly! Installing it is a little tricky but not impossible.

A little work with GPS Gate Splitter (also free) will allow it to route using the BU-353 too.

Then all you need are maps!

As I mentioned, maps are available from either Open Map Chest or Open Street Maps for free. Have to be careful to get the correct version, though. nRoute works with the uncompiled (Mapsource) format, not the compiled (gmapsupp.img) format.

IMO, things have gotten substantially worse for Windows GPS applications over the past several years. Sure, you can use nRoute, I think it was introduced in 2005, and it looks and feels like very old software. Apparently it can't use newer graphics chips properly because it's REALLY slow even on a fast computer. The same computer running Garmin MobilePC or Garmin Mapsource will be much, much faster. I hope Terry was able to dislodge his tongue from his cheek when he said it was "a little non-touch friendly"! But try it... then ask yourself if it's better than the Android software you used.

Personally, I think you made a big mistake switching to Windows when you were happy with Gaia. There are many, many other great Android apps as well: OruxMaps, TwoNav, Locus Map, OsmAnd, Galileo, BackCountry Navigator. And those are just a few (I support all of them with the free maps that I make at Why didn't you just get a tablet with a bigger screen? Maybe it's possible to run these on a ChromeBook (I know there's some Android compatibility but haven't really followed this)?

If you are determined to use the PC, I think that CompGPS Land looks like the best and most modern program out there. So maybe it's worth getting the Pro version? The pro version is free to use for a month, have you tried it?

Otherwise, there's OziExplorer, which is old and non-touch friendly, but it works.

There's also Vectorial Map, but I'm not sure if the Windows version supports navigation (the Android and iOS versions do). About
