To tell the truth G, i only did it directly with the 2GiB NA [US & CA] 1450 because i wanted to see how it would work with the overflow simply because I knew everything would no longer fit onboard [it had everything on board with 2012.20 map originally]. I usually use a 'fake nuvi' flash disc/sd/virtual disk [a 'nuvi stunt-double' as i like to call them] and naturally always use one big enough to take the lot anyway. In the case of the NA1450LM, a 4GiB fake is plenty big enough for everything now np, but i need an 8GiB stunt double for the NA 3597LM as as 'all up' it's over 5GiB data.
It's best not to do it directly online as you said, and so simple to avoid the inherent problems of that anyway. I won't use GE any more because it's flaky even with the real nuvi anyway, and dangerously unstable with a stunt double. MI/MU/WU only for me and they work fine with a 'fake'.
