Hello there,
I have similer problem as here: https://forums.garmin.com/showthread.php?198804-There-was-an-error-installing-Middle-East-and-North-Africa-2015-20
I was trying to complete the maps update on my Nuvi 1310 using Garmin Express for Mac and I run into this problem at the very end "There was an error installing Middle East and North Africa 2015.20."
I tried everything deleted the device, added it again, deleted Garmin Express and installed it again, nothing works, I still cannot update my maps (lifetime subscription)
The device is running on 6.20 (up to date) and has 961 MB still available, also I have 4 GB SD card that can not be recognized, serial number is 1NT127029
Can someone please help me??
Thanks very much for your assistance.
