Summary: This is my first gps device, so I cannot compare it to any other brand device. However, I am very happy with this device. I purchased it as I was traveling to the north in the US and then to Canada by car. Before I started, I connected this device to my computer and got the free updates to the software from the HP website. The screen resolution is fantastic. Very clear maps and directions.
Summary: I have had this unit for about 4 months now. When I wanted to buy a GPS, never having owned one, I hesitated between the Navigon 7100 and the HP iPaq 310. The reviews I read about the HP were mixed. The negative ones were not convincing to me. It sounded more as a critique because the HP does not behave like a TomTom or Garmin. I am glad I bought this unit. One of the complaints was that the HP switches from 2D to 3D mode by itself. To me that is a feature.
Summary: Invaluable for navigation and finding the closest Thai restaurants. Was originally rather buggy, but recent update seems to have stabilized things. Neat trick: with the installation of an SDIO wireless card, such as the Spectec SDW-820 SD WiFi Card (802.11b) and some software tinkering, you can get Opera running on it, for portable internet access, albeit only to unsecured networks. Battery life is rather skimpy.
Summary: I just recently purchased the Hewlett-Packard iPAQ 310 Bluetooth 4.3-Inch Widescreen Portable GPS Navigator. It was easy to use rt out the box. The software was easy to install. I used it twice so far on road trips and it was a sinch to use. A must buy, worth every penny...
