Thread: How to update maps on a street pilot 2720

Best don't use MapSource for compiling .img files from modern CN gmap folders, it's better to use MapInstall exclusively for that or you may get routing errors, even crashing of the unit.

You can simply erase the supplementary map in region 10 [gmapsupp.img] with [Only registered and activated users can see links. ] which will also free up space in region 49 [gmapprom.img] because regions 10 & 49 share space. That way you don't even need to flash a tiny map to rgn10 to overwrite any existing larger supplementary map.

Your last sentence is 'sort of' correct. Because of the space sharing by regions 10 & 49, there are limitations inflicted on one by the other. Reducing the size of the primary map as you did by flashing the 10.5MB map allows a bigger supp map and conversely erasing or reducing the supp map allows a bigger primary map. WebUpdater writes to rgn49 and MapSource/MapInstall/SendMap etc write to rgn10. Another thread of possible interest to you: [Only registered and activated users can see links. ] - also works for rgn49 with SP2720.

Hi, I'm planning a trip by car from Norway to Alicante,ES the next weks and thought I could get my Streetpilot 2720 updated with newer maps..Downloaded CN 2016.20 installed it in my Garmin folder, run it in Mapsource 6.13. and everything crashed....had a lot of maps in the Gamin folder .. usa, atl, europe and more ....no ones comes up...
To make it easy for me..can someone please upload a set of open maps covering the route...Norway, Sweden, Denmark, Germany, Austria, Italy, Andora, Belgium, Holland to give max upload size of 1,7 or1,8 Gb incl. a newer that Mapsource 6.13.7 or newer that will work.. I will then try to get that onto a 2 - 4GB memory stick and transfer it directly to my 2720 .....If You have any detailed tips on who I should do this ....please let me know ..... 28 Hours on the computer now trying to get this done...I'm knackered :-(
