Hello together and merry Christmas :-), I have a W220 Bj. 99 S500 and have a Navi CD Teleatlas 1999 that works perfectly. Now I thought of a more up-to-date version could not hurt 🙂 and ordered me Blaupunkt Travel Pilot Germany 2005/2006 (no DX). When the 3 CDs came I tried out immediately with the result: no navigation CD please change CD. With all three no success. The whole returned and got new. Again with the same Erg ebnis, my Navi (Command D) does not recognize the CDs. The old one is easily recognized and read and funtioned. Does anyone have an idea what the mistake can be? Thanks to you and greeting M
