CoPilot every time for me. I have used it on my iphone and on my ipad, I prefer the ipad size in preference. Sat Navs are essentially an expensive waste of money but for some reason, drivers are suckered into parting with hundreds of ££ pounds to get something that you can get for free with google maps. However CoPilot offers a great alternative being smarter than Google maps and far superior to branded expensive truck sat navs. You will get people saying Tom Tom, Garmin & Snooper are great, these are simply marketed and packaged to sucker you in. I can recommend CoPilot as better than any of these and at the same time it will do the job better, faster and is the cheaper option compared to the branded well marketed products.
