So if I'm driving across several states on a trip, I would have to continually remove the microSD card, load a new metro area onto it, load that into the GPSr, and then move on and do the same for the next large city if I want detailed info like neighborhood roads and points of interest?
Wow - I'm shocked they didn't work this into the unit.
I will use my unit mainly for storm chasing. As such, I want a unit that has the capability of connecting to my laptop and dumping my location into some software that will overlay my location onto a radar software app that I have. I found that the "auto" units (such as the NUVI line) don't have a serial connection that offers an NMEA output for the other applications, thus I went with the 60CSx because it DOES have that output.
THe auto units though appear to be around the same price of this unit, but not only do they come with the CityNat8 software, it is fully pre-loaded and I wouldn't have to worry about reloading other sets...but then it doesn't offer the NMEA output... can't seem to win either way.
Thanks for all the help everyone.
