Just managed to get a UK OS map onto the psp with a route that I followed out in the wilderness.

I used memorymap and loaded the 25K map for the area I wanted to go walking or mountain biking. Zoom in or out to get the desired area in the window then choose map>image export....

Export it to a new folder somewhere on your hard drive.

I then used mapcruncher to add the GPS data and then the global map download tool to upload it to my psp.

Back in memory map I created a route I wanted to walk and right clicked on it and saved it as a csv. I had to edit the csv in excel to swith the columns round and then once again used global map download tool to import it into the psp.

Works a treat

Hope this helps someone
