We are excited about the continued interest and adoption of Garmin Custom Maps by Garmin customers. We are evaluating the performance impact of increasing the maximum tile size and overall tile count. If these improvements can be achieved, our limits may be raised. However, structural differences in the file format between Garmin Custom Maps (KMZ) and Garmin BirdsEye (JNX) will prevent Custom Maps limits to ever reach the overall capacity of Garmin BirdsEye.

Garmin Montana supports 500 custom map imagesMany of you have requested the ability to load more than 100 jpeg of Garmin Custom Maps onto your GPSes. We were able to increase this limit to 500 on the new Garmin Montana. If you're a heavy user of Custom Map, you might want to check it out.As always, this affects the total number of jpegs inside all the kmz files. The number of kmz file doesn't matter.
