Halfords are currently offering the Navman PIN 570 Satellite navigation unit for £99 which is still on offer at numerous other outlets for double that price. This is far more than the stand alone Sat Nav units and has all the extra benefits of a PDA. It is also most suitable for the TOMTOM software and for £99 it has everything needed to find your way about! These were showing as unavailable online a short while back but are now showing as available. please bear in mind that they are available in store at this price. This is a bit older than the TOMTOM one units but is for the price a baragain and a half! Happy new year!
