as the title says im going to update this and have some questions

is the uk roi image in the post the correct one to use

as the device is limited in HD space i think unless i use an sd card there is no way i will fit on 3 d map images and junction veiw etc

also attached is the gramin folder image what do i delete from this before adding new maps

thanks for any help

read a bit more as it a 310 with 5.2 software i think im right in saying the map needs to be a supp.img on the SD card in a Garmin folder for it to be seen. how do you get a supp.img . tried renaming the gmapprom.img but that still didnt work ?

thanks

I don't think a Nuvi 310 can use 3D maps as the 310 is a bit old, at least 5 years old.

Rename the Gmpapprom.IMG to Gmapsupp.IMG and not supp.IMG
