Genau diese anleitung ausfuehren.
I started at V25. This is the sequence I used for the downgrade to V24:
1. Turn the car key to the position that turns on the accessories (radio, nav, etc.), but does not start the car.
2. Turn off the radio.
3. Remove the nav map DVD.
4. Insert the nav software CD V24.
5. Wait for SW upgrade to complete, eject the SW CD, and show the "OK" to continue screen.
6. Remove the software CD and insert the nav map DVD.
7. Click OK.
8. While the nav system was rebooting, I turned the radio on.
9. When the nav screen came up, I turned the radio off, and then back on again.
Once the downgrade was complete and the radio splitscreen functions verified as working, a normal upgrade back to V25 was performed.
Ich hab dan die V26 genuetzt anstatt die V25.
gruss Appy
Ich hab es mit laufenden Motor gemacht.
