I rediscovered this great app/utility recently......it was good before but has developed way further now and there's a discount on the price available to the end of this month.
BARGAIN!
TYRE / TyreToGo GPS route planning software for TomTom and Garmin (uses Google Maps:-)
Various versions available inc USB stick and USB wallet card versions
Pretty low cost anyway (RRP between €10 and €35 dependent on 'package'
but here's a DISCOUNT CODE to save €5AmPsTxKf25
Recommended, well worth checking out!
