Help with choosing Wired GPS receiver

[smallie]

Hi


I have just bought a PDA (specifications and description pasted below), apparently I need to get a wired GPS RECEIVER and I have been pointed in the direction of ebay and here, the trouble is I am worried i'll buy one thats not copmpatible, can someone post in some direct links so that I can just click and buy?, obviously I want to pay as little as possible.

TIA


Compaq's iPAQ Pocket PC combines a 206 MHz Intel StrongARM processor, new hardware, and a sleek industrial design that fits in your hand to create a powerful and stylish PDA you can take anywhere. It offers 32 MB RAM and 16 MB ROM--enough memory to hold a robust package of applications while leaving you a lot of room for your own applications.





Other highlights of the Compaq iPAQ include a microphone and a speaker as well as an audio-in jack. It features an infrared port for wireless data transfer. The Compaq iPAQ uses five buttons plus a five-way joystick. The iPAQ connects to either USB or serial ports. The iPAQ allows you to input data in your own handwriting, by soft keyboard, by voice recorder, or through inking. Both audible and visual alarms alert you when you have a scheduled event.



What sets this Pocket PC apart from similar devices on the market is its sleeve-like expansion-pack system. The expansion-pack system allows you add functionality to suit your particular needs. Expansion-pack options currently include a CompactFlash pack, the ability to attach a CompactFlash card slot to your iPAQ, an executive leather and PC Card expansion pack, and a water-resistant sports pack. In the future, Compaq plans to release a global positioning system pack, so you can turn your iPAQ pocket PC into a GPS unit.



The Compaq iPAQ is sporty and small. At 5.11 by 3.28 by 0.62 inches and 6 ounces, it fits in your hand or slides into your pocket with ease. Don't let the size fool you into thinking you don't get many applications with your iPAQ.



You receive a great deal of Microsoft software, such as Pocket versions of Word, Excel, Internet Explorer, and Money. Compaq also has built-in utilities so that frequent actions--such as switching between tasks, adjusting volume, or changing backlighting--are only a click away.
