Re: Zumo 550 Data Card
Not need for normal operation, no. If you're going to put MP3's or audio books on it you'll want one.
I'm using a couple of 2 GB cards I already had, but I believe the Zumo will handle up to an 8 GB card. I can get an awful lot on 2 GB. If I were you I look for the best price per GB and go for it.
