Summary: It's a nice WAAS-corrected GPS at a great price. And it's RS-232, ya. Way better than that junk in a smartphone. This one can see you wave it back and forth in front of you. Very impressive for the price.
Summary: This is a compact unit that has very fast acquisition time. Easy mounting options, with the magnetic base, or the threaded insert. Easy to wire up and integrate into our application. Garmin did a nice job on this unit. The price is very reasonable.
Summary: I ahd it a few years ago. The GPS chip is SIRF II not III. How can I tell. The specification said 12 channels not 20 channels. So, it is very easy to lose signal. The sentivity is the lowest on the market now. Do not buy it.
Summary: Don't attempt to operate this system on your own while in motion! Everybody accepts the disclaimer at the opening of the application, but you simply can't be looking at the screen while the vehicle is in motion if you are driving!!!
Summary: I am returning this product, because maps must be at least 4 years old. An update to current maps released may 2007, must be purchase at the company web site where GARMIN demanded an additional $75 dollars. What a terrible way to do business.
Summary: I was very excited to purchase this product. I typically have my laptop open while my husband is driving anyway, so I saw this as a great way to get full GPS navigation capability at a fraction of the price of a standalone GPS unit.
Summary: I purchased this unit to use on a trip to Nova Scotia. I own a standalone GPS unit but it does not have Canada in its database. Thanks to the weather and the airline, we arrived in Halifax at 3:00 AM in a heavy rainstorm. The airport was 30 miles from downtown and our B&B.
