Typically MM1.x system requires about 400-500MB disk space to store about 100MB map tiles on a SD card(32k allocation unit for SDHC card). Well the new map repository needs only about 120-130MB disk space.
Nutter,

Looking forward to trying this soon. What do you recommend as the optimal allocation unit for the new repository format? I believe I used 1024b with MM1.4 on the 770, and that worked fairly well. Note that most of the maps will be Google Satellite types, so they're a bit larger than the street versions.

Thanks!
