I read somewhere that the 7015 is limited to 16GB storage simply because that's the limit of the MicroSD cards. Well, I found a 32GB MicroSD and I'm wondering if it could be used. I don't know if the 16GB limit is just old info before 32GB was available in a MicroSD or if there's some other reason. The 7005 will take a 32GB card but it takes a regular SD card I think. Anyone tried a 32GB MicroSD in one? The new 7025/26 says it takes a 32GB MicroSD so that just got me thinking that the limit on the 7015 may just be because 16GB was all that was available when it was first made...I don't know though.
