Hello, I now wanted to update my Navi SW old 760 to the new version and of course use the new DVD. When pushing the CD ROM with me comes the error message “This drive can not read the DVD”. Tests with shutting out, restarting the Navi etc. led to no success. Likewise he can not read any of the three new DVDs. Weird, with the “old” DVD he has no problems to read and navigate. Can anyone understand this problem? Does someone know a solution, except the: go to the friendly and let the Rehcner swap? Many greetings from Lake Constance Olaf
