Thread: Honda Goldwing 2006-2008 Navi GPS Firmware Update Versions 4.60 & 4.70

That's hardly surprising info about the zumo user's 2019 map. What is surprising is that he sent it to you if he'd tried it himself in a GW navi, probably he hadn't and just heard BS from someone else that it works like that (it doesn't as you now know and it's for the reason i gave). If that map's the entire lower 49 or even just all contiguous 48 US states, the 2019.x version was probably the last .img under 2GiB. Current lower states is over by about 10%.

*Seeing as you're going to make a smaller 'short-cut' map img of your 2020 NT, would you like to consider combining it with data from Open Street Maps? You can then see if the OSM can be deselected in settings but still show it's POIs and search functions as is possible with some other devices and map combinations. GMapTool can merge the 2 img files into one gmapsupp.

*Note: Only use Garmin's .gmap data with MapInstall to make a smaller NT .img file. MapSource doesn't handle modern NT map data well and can result in serious problems in actual use on the road.
