With lifetime map upgrades, I would instead buy a device that offers me this option at the time of buying the device. These updates are usually very small so you could essentially update once in 3/4 years and I refuse to pay so much for these small updates.
I decided to just leave my GPS with the update that excludes the south eastern states (such as NY and FL) of the US. The update still covers most of the US, and if I travel east, I'll have to do a region update then.
I tried making an image copy of the Garmin partion with a boot cd, but the Garmin disk wasn't recognized. I haven't tried an ISO image like you suggested (good idea), but I figure, the thought of going through the process several times a year is too much effort since I most likely even go the the locations not covered.
Perhaps the newer GPSes have plenty of RAM where lack of memory during updates is a non-issue?
I remember the first GPS I ever got was a Garmin Street Pilot for about $1000 (still I consider it a great purchase as I get lost so easy). Now prices have gone down so much that purchasing one with a included Lifetime Updates reminds me of prepaid Tracfones with included Double Minutes for life of the phone.
