If you could get some sort of SDIO bluetooth device working on the GP2X, you could connect to a TomTom Bluetooth GPS thingy. The only problem would then be writing the software to load the maps, however it appears that some of the software is under the GPL license (which TomTom follows ) and the source is available to download from here.
Edit: Oops.. That software is for their 'All in one' device, the TomTom GO.
