Is there an easy way for an old man to convert the GPS settings used by ACSI to those used by Garmin,many heated moments have developed during our recent trip to Spain and Portugal, so to save my wife the added problem of dealing with her confused husband help would be appreciated, also has anyone had the problem of the Garmin satnav freezing during a journey which can be a problem when you are at a junction with 10 possible exits. Otherwise the trip was fantastic very hot 43 degs which meant lukewarm beer, and warm wine.
