I Have a Eurospec COMAND (installed by Steve) for my 2004 C320. I bought a set of 2004 Nav CDs for this which work great. My question is, the area I live in is a bit rural and most of the streets are not mapped out. I know these CDs get updated every yr, is there anyway to find out if the newest version has actually mapped out my local roads without buying it first?

Also, I know there are different manufactures for these Nav CDs, any difference between them?

Thanks.

 

Ask the dealer, I know the sales people have access to the latest CDs for demonstrating Comand on test drives.
