Light years ahead of all others, but useless without available upgrades
6 April 2012
Summary: I love the unit. The one I have is one of the first 300s available. Being a professional truck driver, I wouldn't be without a GPS. Although the 300 wasn't intended for trucks, it has bailed me out of many 'what now' situations. Down side, and a BIG one, that effectively black flags the entire product. The unit I have is NOT software or map upgradable without a factory SD card and it's NO LONGER AVAILABLE OR SUPPORTED.
Summary: I've been using this GPS for almost two years. It works well enough, but it appears that bankrupt Delphi will not be supplying map updates. I am a road warrior, and I am already running into problems where the maps are not accurate, or roads are missing. Also, it won't save a destination unless you are on a road, so if you are in a parking lot, down a long driveway, etc, you have to go back to the road to save the location.
Summary: This GPS is one of the best I have used. I had a JVC and it was poorly constructed and never got a good signal. This Delphi NAV300 on the other hand is awesome. It is small and not big and clumpy like the JVC I had. It's size makes it very easy to take where ever you go. If you are interested in a simple easy to use unit I recommend the Delphi NAV300.
Summary: After owning a few Garmin GPS's the Delphi NAV300 requires a new learning curve. To the user that likes to have a lot of information on the screen and a few tucked back for the trip this is THE GPS. It requires a few (did I say FEW ?), more like many, references to the owners manual to learn how to get the full potential of this unit. Really, it's fun to use once you stop playing with it on it's internal battery and install it in your vehicle and turn it on.
Summary: I bought it because I needed a GPS so when I go out of town (bigger cities). I should have done my homework on this item. This GPS is nothing but JUNK!! To all buyers out there, avoid this one!
