jefflins I am currently using the streetpilot c330, sure its form factor is nothing to rave about but it gets the job done admirably.
I have had the c330, Ique M5 and i just returned the axim x51v (now before you axim lovers jump on me, I think the x51v is a great handheld, I just needed it for a navigator and not a PDA).
While driving on I-270 (MD state) we have local and express lanes, the x51v with the dell gps kept telling me to go to the local lane take an exit and immediately get back on the interstate and then back to the express lane. THis kept going on in a cycle till I got off 270 and got on the DC beltway. Note that I actually needed to keep driving on 270 straight till I got on 495, no exit nessecary but the dell GPS
This is extremely annoying, idotic and at 75 mph unsafe. once on smaller roads its navigation was good and recalculation was faster than the c330. Also the dell has a faster satellite acquisition time comared to the c330.
The c330 has consistently performed well and one major adavntage is that its preloaded with all of US. My suggestion ..if the x51v is primarily going to be used as a navigator then youre better off with the c330.
note that i didnot once mention the ique m5 ...its a piece of junk.. good at nothing.
Prices (shipping taxes included) - The c330 and IqueM5 cost me in the high 500s and the X51v + dell gps (non BT) mid 500s
agian as a handheld I must again say the x51v is very good, and I have no experience using the x51v with other GPS bundles.
