Version 5.10 is your firmware. Firmware updates are free always. No matter if you have lifetime maps or not.
First check to see if you have the latest Garmin Express installed. Click on the gear icon on the top. Then click on check for updates. You should be at version 6.11.1.0
This was my problem too. Loaded latest "express" and now it works on my 660. Updating now......at 1.5 hours to complete (it says). Also told it I only need US, not the entire continent
