I have been using Navman GPS for about 5 years now and have used other systems in other cars. I prefer Navman to others and find instructions more logical etc. Irish maps are not excellent. Even the five year old maps, however, are good for major cities such as Dublin, Cork, Limerick, Galway etc. but otherwise coverage is quite poor other than the main N roads. I have also used AA Navigator. Maps are more comprehensive but voice instructions not as good or "logical" as Navman's.Has anybody had any experience with the Navman GPS System?
