Hi, can anybody tell me the latest software available for the accessory navigation on the pre-2000 E class? (the one that sits on the dash not the COMAND), I've looked on the NAVTECH website but don't see anything that's compatible with car. My stealership can't tell me which version I have either and whether or not that's the latest one..( I checked the version info on the screen, but they said it doesn't help???)

Thanks in advance!
