This is going to be half question half request

From what I've learned for my model of Honda Accord 2003-2005 I should look for Orange DVD for the Nav System. So the question is where can I see the latest version of the maps and the areas covered in that version and where can I download it (the Europe version)?

Another thing that I want to find out is whether I can use White DVD for mine model. Cause I already found 2017 maps from White DVD.
Is there some upgrade procedure that I can do to upgrade from Orange to White?

Any advice/info will be more that welcomed.

Thank you all in advance.

 

That is an interesting question. I expect that update DVD's are specific to the head unit and that versions for newer models would contain extra information that could be incompatible with older versions.

You could call Honda and ask their tech tem if your model is still supported.
