x2 on the maps - Garmin you have to pay for updates, $70 a pop(!)
just a heads-up for anybody with this same complaint...
they fairly recently started a lifetime update deal...which works with all the Nuvi's and some of the StreetPilots (plus some more models, but those are the two I own, so that's when I stopped reading)...
Garmin lists it for $120...but I found it for just under $100 online...
four updates per year, for the life of the unit...but it can only be used on one unit...
it's not free...but it beats $70 for a single update...
As far as which one to buy...you also want to consider the "other" features. Mine also has bluetooth, mp3 player, external SD card slot, audio out port, and a traffic receiver...
If I'm traveling along on business, my favorite setup is to plug an FM modulator into the audio out port, and I can listen to mp3's through the radio, then it pauses the song when it's time to give me a direction, then resumes...and also pauses if a phone call comes in (uses radio speakers as speaker, and has a mic built into the front of the Garmin).
if you search used...I'd definitely recommend something with Text-to-Speech. The Garmin Streetpilot c330 was a very popular model (PepBoys, Walmart, everybody else seemed to have it), but it didn't have TTS. the c340 was the lowest model that had it. As info, a TTS model will say "turn right on Brown street", where a non-TTS says "turn right in .4 miles"...which means you have to look down at the unit to see the street name.
I have both a Garmin StreetPilot c550 and a Garmin Nuvi 360. Very satisfied with both.
