Touring Best map for touring Germany?

i've got a satnav, but i thought it would be better to have an old fashioned map as a back up on my trip.Any ideas which map would be the best?

 

Ha Ha nice one just to make myself clear which make of map gives the best info

 

Thanks for the kind offer Steve, but I've ordered a couple of michelin maps from mapsman.com they seem to have a great selection at pretty good prices,I'm heading to the Harz mountains for 4 days before going to Chemintz for the German moto gp

 

Cheers, i think I'm sorted with the maps I've ordered, i get the ferry on Sunday,Pissed off with my zumo though as it's not accepting any gpx files now plus i put a memory card in but it's not taking any gpx files either so i have just entered the final destination into the zumo and i'll use the good old fashioned maps for various routes
