Hi all, is anyone else experiencing poor performance. I have constant freezing of the maps, today it froze when I left Birmingham airport, travelling to Bristol. The gps still worked, the colour display, and in maps small menu worked too, but the maps stayed frozen on the location in Brum, today... I have had this around 2-3 times a week since new. Also it has sporadic hang ups on phone, dialling out but no audio connection, and music, not allowing selection of any music at all from the phone, iPhone5. The sat nav glitch is the most annoying I must say.
