I have downloaded the europe 2015 dvd1 and burned it with imgburn, slowest speed possible on Verbatim. After I inserted it, it works fine for 10 minutes, after that it tells you to put in the desired adress again, but it wont let you do it. If you turn off the car and have a coffee, it works fine again for 10 minutes etc.
It worked fine with the 2014 map. But now i can't go back to the 2014 map. It has the same problem.
Some days before the new 2015 map i changed the driveunit with laser and lens in de dvd unit, because the old unit didn't read the dvd anymore. It worked fine for a couple a days with the 2014 map, after changing to 2015 maps the problems began.
Car is a bmw e39 530D touring of january 2003. The firmware is updated up to v32.
