I asked previously about the Chinese Truck Sat Navs but reading all the comments and links from that decided not to bother. We have a TomTom Go Caravan Sat Nav which I have been happy with when using through France & Spin with a caravan. There were a couple of occasions though, around (and through) Madrid and later around Bordeaux where the Sat Nav got it very wrong!! Now we have a motorhome 7.4m long I am a bit more cautious so thought a back up might be useful. Does anyone know if co pilot caravan is any good or am I better spending a bit more on a truck sat Nav. I would prefer the back up to be on iPad. Or maybe just stick to Tom Tom , common sense and maps. Thanks
