Micro SD card
I have the 7200t GPS and it has a 2 GB micro card. This card looks to be almost filled and I would like to upgrade to a 4GB micro card. My question is two fold. First what kind of mirco card do I buy? My card just says mirco card on it, It doesn't say HD or anything else. So what does the card have to say on it to work in my GPS. Next, when I do get a new card what is the step by step procedures to transfer everything from my 2GB card to a new 4GB card. :?
