Didn't know that Peter. I've not tried my Mio Navman to see how many waypoints it can take. Most journeys where I use it are to find the final destination, to get me back to a road I know, or for potential traffic/roadworks etc. notifications. Garmin were good for setting up one's own routes, but the only recent one I tried was defective, so never got to test much in the way of it's facilities.
Frank, stick to the maps/charts - my preferred nav method! Blog is looking great.
Giles, I can just imagine a TomTom with a mix of Peter Sellers bumbling Detective and the Policeman from 'allo 'allo giving directions...

Cheers,
