Dear all.

I have A5 Sportback. i has problem on my navigation system.

Whenever i start a car, my navigation system is being initialize.

Turn off the engine and 5 min later, if i start again, Navigation is initialize again.

i visited Audi Service Center, but they mentioned they couldn't find any problem.

if you know, this kind of problem and solution, please let me know.

Hope all of you guys have a great day.
