HI DK,
You will possibly be on a fools errand, a couple of my pals have XKE Ht and conv with the same problem, one of them is so bad at direction if he fell into a box of nipples he would surface sucking his own thumb.. so he tried really hard, finished up going the Garmin route, at least with that one you can spend 20 mins and update it every 6 months, my other pal like me in my Jagwah well we have good inbuilt compass and a typical Mans mans ability NOT EVER NEVER to ask directions, I sometime need to cos times money..
My regards Peter R-B Lancashire
