A quick bit of googling and I found this;
It's a serial to bluetooth pipe. Bit pricier than a cable but should do the job.
Just had a look at the Maplin site and the cheapest SatNav I could find was Ã‚Â£70. So that was a good buy at Ã‚Â£50. I do agree that it is a possible cheap option as far as the hardware cost goes, but it may be more work to hack. Just when you have got it hacked, that unit may no longer be availble so you start again, figuring out how to hack the latest "cheap" sat nav. Although the N810 is more expensive I think any software developed for it should be usable on more devices since Nokia is using a version of the Debian linux system. Any code written for the N810 will also run on the N800, provided it is running the latest version of the operating system. It should also be possible to use the code on Linux versions of cheap laptops such as the Eeepc.
