Thread: nüvi 3x0 SD & Map Size Limits

Is not true, because some forum and garmin said, with old serie gps, -----» not working with SDHC more 2gig, is not true.

I already made test via mapsource and garmin topo map of canada with about 4gig of the nuvi 360 and has worked wonderfully! on a SDHC 4gig

I've combined europe and north america in one gmapsupp.img on a SDHC 4gig
the big problem, I think I'm poorly installed or unlocked, I'll make test

P.S. no new update firmware for my gps !

if is because more 2gig is problem, why 3gig topo maps workk well ?diff betwin topo and city map ?
and is not my install and not my unlock because the bam bam IMG maps have the same problem , map is not locked, but search address mode not work !

You might give this a try...

I will perhaps again later test, its a good idea for one test

i confirm, on streetpilot c530 not search address working and in my nuvi 360
