IMO, the faa with going to updates every 56 days for all vfr charts made me look at Ifly connect. I went and bought a second sd(16gb) card(<$10 at walmart) and now alternate between the two media cards I have. In the past for my 740 , it would be about an hour to update using the 740. This is again , getting it out of the box , powering it up, going to update , yada yada yada. Not I just grab the sd card that is not in the 740, plug it into my computer and update while doing email, etc..< hour to update all files Put an email reminder when they expire and Walla , there you go. Only issue I have see is all my flight logs are not on one card, I can deal with this .
This seems much easier. Just wanted to pass on my experience as updating the entire faa vfr db over the 740 would have been several hours. Much quicker and simplerwith connect and my laptop that on the 740.
p.s, make sure your laptop/desktop has a sd media reader, else you'll need to buy one for a usb connection.
also , now I have a backup sd card just in case it gets toasted, corrupted.
