Support Thread for the TND 500, TND 700 or future Rand McNally products. (part two)

I just looked at the Micro SD card my wife picked up for me... It's a 32gb class 4 .... I will pick up an 8gb class 10
before I contact you, Mark..

I am dealing with the TND 720

 

System file missing call customer support error after updating rand McNally 720. It is the weekend and no one will answer. My device was working fine before trying the update. I'm so mad right now because I need this freaking thing to work now and what promised to add features and ease of use ended up breaking my device. Diagnostic and repair finds no errors. This is the most recent update that requires an sd card of at least 8gb. I had a 32gb card already installed before the update. I've tried everything. Anybody have an idea about how to fix this now?

 

mark will probably be able to give you a hand around 5pmish i'd imagine, i think atm he's trying to have a life

 

Ok Mark.....i am going to try to update one of my 720 units today...

hope all goes well and i dont need any help...

 

when I did mine, I did the map update first and only, worked great and gave me most of the new features without any problems, i didnt even bother with the "device update" fwiw
