Max size of SD card

Hi

I need to activate / unlock lifetime maps on my new Zumo 660LM. Everything points to Garmin Express being the way forward. The main update listed on there is the Full Coverage of Europe version 2015.40, at over 5Gb. So I need to buy a microSD card.

Please can someone tell me the maximum size card I can use? Bearing in mind the map update is 5Gb I guess a 16Gb would be wise, but some googling tells me that the SD card will only go up to 2Gb which is no good. Can I use a MicroSD HC card?

Once this update is downloaded will this unlock my LM availability?

Thanks for your help.
