I have been assured, by Mercedes Benz of Harrogate, that the TMC enabled DVDs for COMAND satnav will be out early in the new year. they have this info direct from mercedes. so it is only 18months late then! I have just taken delivery a 55reg SLK and it was equipped with the same version (4.1) of the DVD the older SLK (2004model 54reg)was. I emailed Mercedes via the contacts page on www.mercedes-benz.co.uk and asked why i received the latest model car and yet only got the old version on the DVD. they said that 4.1 is the latest version but I expected the upgraded version. anyhow they are sending me it, when it comes, at no charge. I thought it may be of help to any potential, or recent buyers who were unaware of this issue. I havent looked thru the forum recently, so if this is a duplicate of other threads in here, my appologies for taking up space.
