I am finally moving into this millennium and getting smart phone which will be an iPhone 6, that I want to use for offline navigation with the built in GPS so as not to gobble up my data plan. My preference would be to down load the Garmin street map data base for the US and/or charts as I have been happy with Garmin in the past. However, I am concerned the data base size of the maps and charts may be too large for a 16 GB iPhone. After an extensive online search, I can not find the MB or GB size for either the Garmin street map or chart data bases. Does anyone know where I can find these data base sizes or if navigating like this is really doable? Michael Wilkie Grass Valley, CA

I have the Garmin Blue mobile on my I-pad with charts dowloaded for all of North America east of the rockies and it is 1.4 gig of data with app.. Your I-phone should handle this easily, so not a problem Joe Pica M/V Carolyn Ann GH N-37 http://carolynann-n37.blogspot.com/ MTOA#3813, AGLCA #5485

Michael, I've had my iPhone 6+ for about 8 months now. Bigger screen for older eyes. Had the foresight to buy the 64 GB option. For offline street navigation I'm using GPS CoPilot. The N America detailed street maps take up 9GB! Your first continent is free, additional continents can be purchased. This app works great, doesn't use your data plan and doesn't go dead when you drive someplace without data coverage. I haven't tried any charting apps yet.

Correction. The N American street maps for GPS CoPilot take up 2.4GB, not the 9GB I previously stated. And yes, updated charts are regularly available.
