| Customer Reviews: Average Rating:  Rating : - Works Great With Both Treo 650 And Gateway Laptop I actually got this GPS in a bundle with the Mapopolis NavCard. It is very easy to use, and I found it to be very reliable. While I added it as a trusted device to my Treo, Mapopolis can't remember what GPS to use (minor issue that is not the fault of the GPS). It has great battery life - I've never used it for the 8 hrs advertised, but it is good for use around town. We used it exclusively while on vacation for 4 days. It acquires coordinates in under 1 minute from cold start. The beauty of this being a bluetooth device is that it can be used with multiple devices - Treo or laptop in my case. So if your device that receives the signal dies or gets lost, you still have a GPS building block left. I highly recommend it for the Treo if you get the Mapopolis bundle. + See Full Customer Review |  |
