Lack of data

[Palfers]

I have a zumo 660. Few years old now. I’ve just updated the maps but now when I try to enter a new destination address I get a notice ‘ No Data Available’. I have a 16 go card fitted. Do I need to get a bigger sd card?? Thanks all.

Welcome to Zumo User forum Palfers.
Like yourself, I have an aged 660 LM on which I have only recently updated the maps to 2025-10. The update shows 5.1GB which is too big for the Z660 internal storage. I used MapInstall to update the maps to my SD card (32GB) but your 16 GB SD card should be plenty big enough.

Hi thanks for your reply. I’m a bit puzzled then as to what to do next? It worked fine before I updated. Did it through the Garmin site so assume it’s authentic?

May be a silly question but do you have Garmin Express and Mapinstall on your PC/laptop?

To be honest I can’t remember which route I took but I will check later
