I am original owner of my 2006 SLK 350. I don't drive it during the winter and keep it covered in my garage. Well this year I didn't start it enough and the battery died. I jumped it and and all went well and figured I would drive to give the battery time to charge. However a soon as i started out I noticed that my Comand Center/ Navigation was not working. I hit the power button and the Mercedes Benz logo comes up and then it just shuts off. I tried ejecting the DVD in the trunk and re-loaded it but still same problem. Everything worked fine before I put the car away for the winter and I have never had a problem with it until now. I read like 80 pages of post and didn't see anyone who had this exact problem. Any one have any idea what could be causing this and what is needed to fix it ?
