Wanna have a GPS lately for my car. I have to take long distance business trip from now on. So I’m wondering to buy a simple GPS only, or also get a DVD with GPS together to have more fun? I’ve found this Eonon 7 inch car DVD gps Navigation with USA-CANADA Map seems quite good, cool featured but not so expensive. . But the problem is, is it illegal to set the DVD when driving? If I can’t avoid this problem, should I buy this GPS only? Or do you have any other good items recommend? Urgent for your kindly advice. Thanks in advance!
