Dell's software and hardware offering is but one version of many choices in this area.
1) Hardware for GPS
1a) Wired / Async - to me the simpliest of the GPS. Directly attaches to Axim via a cable that will both power the Axim and GPS unit. Normally 2 cables actually. An adapter that plugs into the bottom of Axim and to the GPS Unit and another that plugs into the adapter to the CIG Lighter. I personally use a iGPS 360 with wires all over the front seat and SEIDIO G4850 which is a cradle/mount for Axim with built in GPS and Speaker.
1b) CF card / SD Card - This option the Axim supplies the power to the GPS directly. To keep the Axim powered use the in-car cables that came with Axim. Most do not like this option, becuase of how thin the these slots are and stress that the unit may put on the Axim. Other like it because you can walk around with the Axim and the GPS.
1c) BT (Bluetooth) - This option the Axim power itself and GPS powers itself. For longer drives there are Y-cables that allow the Axim and GPS unit to share the CIG Lighter for power. BT units though tend to have 5-8hrs of battery life, so charging at night is normal. Most like these units for the ability to place on the dash (fornt or back) or even in glove box and "forget". A few have problems setting up the "pairing" but normally that works out quickly. Since the unit is small , it can be placed in your pocket if you want to walk around with GPS.
1d) Combos. There are BT "shoes" for CF Cards. There are cradles with wires to supply power to external GPS units. Some GPS Units have interchangable adapters (iGPS 360 can be wired Async, USB for laptops, CF plugged in, and BT)
2) Software for GPS
2a) iGuidance - the parent or cousin to Dell's. This software comes with 3 different versions for Laptops, PPCs, and UMPCs. And the choice is yours when you need it. I use this software mainly for long trips, the only big wish I have it would give more turn notifactions per turn. Otherwise you are looking at the screen to much while driving. Maps for all of US take 2.2G, maps are only down the state level.
2b) Mapopolis - simplest of the GPS Map software. Not to say that it is below par. Just that interface is not a "finger" pushing interace, just a standard Window style. Foot print is small, uses counties to keep maps sizes small. Issue to me is long trips, you need to use the state highway maps, then load the counties maps along the way for stops. Not big issue when you run around your home town area, but can be on long hauls. Nice side is you can you-can-try-before-you-buy for 10days. I also like the programable turn time (more later)
2c) Tom Tom - my understanding it is right up there with the single use units.
2d) There are more GPS Maps... Desinator, Route66, and....
3) Other hardware
3a) Memory Cards - Eiither choice will be needed because maps of US (whole) can run into the 2.4G range.
3a1) CF Card - I place my maps on where because it is harder to change then the SD cards. If you use a CF card then the CF GPS are out.
3a2) SD Card - I place my music here because it is easier to change.
3b) Some to keep your Axim safe while driving.
3b1) Cradle - Mounts to Window, AirVent, CupHolder or Hardpoint. Allows the Axim to be seen while driving. Again I like SEIDIO units, others like Akron Units. Issue here is besure to know the limits of the Cardle. Like Axim only, with extended battery, with Silcon or other protector.
3b2) Silcon protectors - works well when you do not have see the screen - My wife likes this choice with iGPS and Mapopolis - since she is wearing the Axim like a pendant. Mapopolis can be setup to start telling about a turn 75 seconds before the turn and then every 15 seconds until the turn. Helpful in new areas.
Look around some more before buying - look at
BUYGPSNOW, there bunds that come with software and hardwares. Key is to think about the how you are use the Axim while driving. Example my wife wears as pendant so Axim volume is enough. I use the SEIDIO for longer driving, with radio and kids, and I place the Axim on passenger side of car (so it visable but not where I play with while driving) I need a sound boast so internal speaker is helpful.
