As far as I can tell, Google does not support GPS inputs on Windows or MacOS; only on a mobile device (iOS or Android). I'm not sure how well it does, but windows maps with the GlobalSat BU-353-W10 puck may be your best bet, if you absolutely have to use a Windows program. The 353-S4 puck will not work with that program. Another option would be a placefile for GRL3 (either of the two GPS pucks I mentioned will work with GRL3), but you'll be at the mercy of how often that placefile is updated. I personally use a standalone device that's regularly updated, with my tablet as a backup. I'm not a huge fan of clutter on my radar screen, so I keep it relatively clean other than major highways and county lines.
Hey thanks! I use GR3 with shapefiles for roads. I have downloaded google offline maps for my phone but wanted to also do that if possible for my laptop. Its a challenge navigating Google Maps on just a phone while chasing!
It seems like we used to have it working really well (circa 2010) but now it’s going backwards. I wished it was getting better with time, but after Garmin bought DeLorme it started going downhill and I don’t see it recovering anytime soon.
I did do a quick search ... nothing comprehensive, but, Google Earth does have GPS support. That seems like the way to go, if you want to stay with Google's mapping capabilities. I have not researched how much work this would be or how well it works.
I wonder what the bandwidth requirements are for Google Earth on a poor cellular connection? I should fiddle around with it this year and see what works and what doesn't. I think regular Google Maps would be the way to go but who knows at this point! Or possibly Windows Maps with the Globalsat W10 GPS receiver? Lots of unanswered questions.
There is one way I know of to overlay that and radar data with no cell service, and that's Baron Mobile Threat Net. Once you get MTN installed, the box turned on, and the service started, you just contact Baron and they get you a GPS and mapping upgrade, and that will give you all your streets and such, with a GPS beacon, as well as radar data, all delivered by satellite.
I use a combination Baron Mobile ThreatNet (love it, never crashes, works everywhere), GrLv3 and StreetAtlas 2011 and supplement with Google Maps on my Samsung Phone and Google Maps. I still have a Windows 7 laptop which I managed to preserve even after they did that darn forced update to Windows 10 years ago which affected many people. My laptop is 9 years old, taken many a beating (dust, falling out of the car) and still working.
