The product package includes1. CF GPS receiver.
2. PocketMap Navigator Software 30 days trial version.
3. Antenna booster for in car use (it does not require any power from car)
I am using it with my Dell AXIM 5, PPC Windows 2002 system. Once it is up it tracks on average 6 satellites (maximum display limit is 12 and the maximum i have seen it track is 8) with a CEP of 17' on average. On a overcast day antenna is must otherwise it doesn't track any satellites on my system. On a clear day it works well out doors without the antenna.
What I like about it:
1. It doesn't drain too much power (I don't have to recharge my PPC more often)
2. Its easy to install and use.
3. Reasonably accuracy (25 CEP per specs - in most cases its better than that)
4. Navigation software comes with voice navigation (voice itself is digitally synthesized - so its little bit hard to understand). The software has nice list of POI's (grocery stores, motels, fitness clubs etc)
What I don't like about it:
1. Map software is 30-day trial version. At the time of writing this review its price is $...
2. Navigator software doesn't give you route optimization options (e.g. you will prefer using highways/interstates or other road ... etc)
Note: For Dell Axim 5 users - it takes up the CF slot and you can't use CF slot for map storage.
