Last time I went for a ride on my bike (that's the loud one, not the one with pedals) although I know the aera quite well I let my eTrex Legend do some routing.
I wanted to take some arbitrary scenic route, so I switched the 'avoid highways' (don't know if it is translated that way by garmin) option on in my routing settings.
Guess where it tries to direct me? Straight to the nearest Autobahn.
So does anybody know if this is
a) a mapping failure
b) something not yet possible with mkgmap
c) a bug in mkgmap
d) a bug in computerteddys map
c) a bug in garmins routing soft-/firmware
I know there are other places to ask this and get a more technical answer, but I just wanted to check for similar experiences first.
