Hi, I have a Windows 7 64 bit pc which is up to date, I'm trying to update my Garmin Nuvi 2595 from 2015.40 City Navigator NA to 2016.20. I have the latest Garmin software (GE 4.1.8.0), GCPI (4.2.0), etc... I am NOT using wifi, but direct Ethernet cable connection to a high speed connection. I have verified that I have connection to the Garmin servers. I have cleared 22 GB of space on the computer where I am trying to save the map. I also have 5.69 GB of free space on the device itself. However, I have tried Computer only, Device and Computer and Device only with no success. Garmin Express just says "There was an error installing the update". I have even tried to simply download a single vehicle icon without success. It just says "Failed".
I have tried uninstalling and reinstalling Garmin Express. I have a lifetime map subscription. The error is very vague and I don't know where to look next. I tried emailing Garmin Support - b/c their phone hours are no good for me. Their only "worthless" suggestion was make sure you're using the Garmin cable and you're not on wifi. Yes, it is the Garmin cable and my device connects to the software and goes into media transfer mode.
Does anyone have the answer?
