Hey everyone. First post actually on a forum before. Now I have JDM accord CL9 automatic. Fantastic car had a new gearbox already. ( hard lesson learned there.)

Now my question to everyone is as follows. My Honda has a Japanese Navi in it and I know I can't change the language in it, so I bought an Euro Navi that is working in the Euro car but when i plug it into my Accord, nothing works at all except the air-con controls. I even bought the DVD player thing that came with the euro Navi it does have a different plug though. Anybody got a clue. I have googled extensively with out much luck and now I thought of the forums. So here I am.

PS I live in Swaziland and there is barely anyone who does radios around here.
