I own a 2005 Honda Accord EX V6 coupe, with navi. It has the DVD player in the trunk with the 2005 Navigation DVD in it. My question is, is there somewhere where I can purchase an updated version of the GPS DVD? THere have been many new roads added where I live since 2005 and it would be nice if my GPS had them. Would the dealership be the best bet? I tend to stay away from dealerships due to high prices.Also, if I can use an upgraded disc, will it just have updated roads on it? Or could it possibly have updated features such as real time traffic reports, roadblock warnings, etc.??Thanks for the help...
