0ur opinion: :Garmin has introduced two new in-vehicle GPS receivers for use in your car or truck, the StreetPilot c320 and Street Pilot c330. We'll be discussing both in each description as both are virtually identical with one key difference. The c320 comes with Mapsource City-Select award-winning software on CD (for installation into a notebook or desktop computer) and uses a 128MB SD card which allows you to download a particular region for GPS mapping as you drive. The c330, on the other hand, comes pre-loaded with highly detailed MapSource City Select street data of the entire United States, Canada, and Puerto Rico. The database features an industry-leading five million-plus points of interest?including hotels, restaurants, gas stations, ATMs, and attractions. So, if you do lots of long-distance continental driving, the c330 may be the better value for you. lf you usually stick to driving within a section of the country, the c320 might just be the best for you. Both are exceptional units but you must choose which is best for you. Either way, you can be assured that you'll get where you want to go easily and comfortably. Choose between a three-dimensional navigation view or the more traditional ?bird's eye? overhead view Each boasts distinctive and sleek styling?the only buttons are a rotary volume knob and an on/off switch. The device is secured by a suction-mount cradle that fastens to the windshield for easy portability among vehicles. Users can customize their unit's appearance with an array of colored faceplates (sold separately).

* Good unit ...
The GPS is very accurate, to within a few feet. The maps have nearly all businesses and restaurants, but not all. I was not able to find a qdoba in some cities, but was in others.
The touchscreen was remarkably accurate, and easy to type on.
Customer service on the unit was also very friendly and helpful, and spoke english as their first language.
A 5-star product.

Excellent Affordable GPS
I bought this GPS two years ago and it has worked great ever since. It was affordable then, and even more now. It doesn't have all of the bells and whistles the new ones have, but it makes up for it by being extremely easy to use. Out of the box it takes literally 5 minutes to learn how to use.
I also like this exact model because it doesn't have an on-board hard drive and therefore you can add any size SD card to it. This keeps the cost low as SD cards have dropped in price lately. A single 2 gig card will hold maps of the entire US.

* Does exactly what its supposed to do ...
A great basic GPS device that works exactly as advertised. Text to speech may be a nice perk, but you really don't need it, since a quick glance at the display gives you all the information you need.
There are limitations you don't get with a higher end model however. You can't customize your route on a PC and upload it to the C320. Sometimes, it takes you on a wierd routing. It *will* get you there however, and if you're unfamiliar with the place, it probably doesn't matter if the route's not the most intuitive.

Garmin - Inaccuracy at a price
I found one of these for $200, and based on the reviews I figured I'd be pleasantly surprised.
I thought wrong.
Not only are the maps highly inaccurate, but it doesn't give enough notice on when to turn, so missing turns is quite common. The routes this thing takes aren't usually the optimal choice, and it likes to avoid the highway even though it's on the default settings. So you end up taking a ton of back roads that really slow down your trip. I recently missed a trip to the movie theater because of this unit. When it said I was arriving at the destination, it brought me to a field. That's right, a FIELD.
Not only am I out the $200 for this inaccurate POS, but I'm out $20 for the movie tickets. Thanks a lot, Garmin.

* good GPS ...
I love Garmin GPS products but I wish I got the 330 because this model does not come with the pre-loaded maps of teh USA. If you are going to buy a GPS have the maps pre-loaded. IT is just a lot easier then trying to find an SD card big enough for the USA
