Hello All! I am considering the purchase of a 2002, 2-door Honda Accord Coupe or a 2003, 2-door Honda Accord Coupe. In order to save money, I am considering the purchase of an after-market DVD flip-screen navigation system, instead of paying the extra high-cost of a factory-installed system. Can someone out there suggest a system that is compatible with the cars I mentioned, and also how much it would cost including installation. Thanks!
