Creating a micro SD card?

[BBQ BOY]

Hey y'all. I just bought a new double din Navigation head unit for for car. One of the many media features is that it excepts a micro SD card. What I would like to be able to do is create a micro SD card from my Mac. What will be on the card are photos. I am not sure if you can put music or movies on it but I have an 80G ipod that I use for that. If I can put photos and images on it I can have them on the screen for the start up screen or as back drops. It would be great to have a photo of my wife and young children on there or a entire library of photos.
Anyway, I am not very computer savvy and need some guidance on how to do this.

Thanks

I'm not sure iMac users are the experts to ask in this case. You might want to try another forum.

buy microSD card, insert into this transfer files onto it as you would a regular SD card, take it out and voilà!
