>When I bought my Map76cx I understood the max storage limit for a microSD card was 2GB. Has that changed?
Yeah, read up on SDHC - the wikipedia articles are pretty comprehensive. Different devices support different classes of SD/microSD, though. I just ordered a Garmin Oregon 550, with three different size of microSD card just to be safe: 2Gb, 4Gb, 8Gb.
