Pros:
- Quick GPS connection with A-GPS made by GlobalLocate (finds satellites even trough thermally protected windshields, where other older GPS units cannot)
- Up to 2 GiB of storage on a mini SD card (for maps, track logs, etc.)
- Integrated camera and microphone could be used instead of note-taking with pencil.
- GPRS/EDGE connectivity for real-time tracking anywhere, wlan where available
- Compact, all in one (like a big GSM phone)
- Windows (relatively easy software development)
Cons:
- Windows (has to be rebooted every few weeks to regain leaked memory)
- Battery life (around 4 hours with GPS and no WLAN or Bluetooth turned on, can be prolonged by turning off the display, probably also by turning off the GSM part...have to tested that once)
- Mini SD card can easily be lost (using sellotape to keep the second one in the slot for sure)
- Some software doesn't adopt nicely to the square screen
- No GPS mapping software that would use ALL the device's features seamlessly (GPS, camera, voice recording, connectivity) exists ... yet.
- GPS traces seem to be "smoothed" - in sharp corners track continues straight and only turns slowly later on.

Pros:
- Integrated 2 GiB of storage of which around 400 MiB is free for user apps and data. The rest contains the TomTom maps of Europe.
- Integrated microphone could be used instead of note-taking with pencil.
- No COM port splitter software is needed. Hardware wise the GPS is on COM1, but the applications can all access it simultaneously on COM7 at 4800,57600 or 115200 baud.
Cons:
- No phone, no camera
- Not sold anymore (and this only one month after I bought it)
- Compared to AD-850 loses signal more often.
HP iPAQ 3970 windows PocketPC 2002
- PDA devices
- Getting it working
- Flash the PDA BIOS to version 2.10.
- Flash the NAVMAN 3450 firmware to the latest version - only if it's the external antenna version!'
- Install the HP IPAQ SD memory card update version 1.1 , allows modern 1 GiB plus SD cards to be recognised.
- Install SmartST serial drivers version 3.1.6 (solves the sleeve not recognised problem).
- Once you identify the com port assigned, and set the baud rate, you should start to get a data stream. In my case it was COM6 baud 56700.
- Using a simple GPS data logging program, you can collect and store track data.
- If the antenna connector will not seat, do not force it as this will bend the central pin or squash the plastic sleeve that surrounds the central pin. If it is bent, very carefully straighten it with tweezers, although you might need to replace the connector port (strip and solder job). I recommend getting an MCX male to SMA (threaded type connector), and an SMA to MCX female connector if you want to plug and unplug the antenna a lot. The SMA threaded connectors are self centering so are much better. A cheaper alternative is to make a pair of short fly leads with the MCX / SMA connectors on each end, be aware you will get signal strenght loss, how significant this will be depends on the quality of the adapters / fly leads.
- Alternatively buy an antenna with a SMA connector instead and use an adapter.
