Not sure if this is the right forum category...
On a whim, I decided to try and pull up my Google Maps version of some of my KMZ maps on an iPhone 5...and it worked! I hadn't thought about it before, since I'm not an iPhone user. Who said KMZ files were only for Garmin lovers?
If anyone has an Android powered phone, can they try the links and see if they work?
