Hello,

I have the problem of memory failure: "MMM-U220044 Control Module Configuration Memory Corrupt, System Internal Failures, Data Memory Failure"

I bought the car with some maps copied on Verbatim DVDs from the year 2013 and I already had the memory problem. Then I downloaded several maps of 2017 from the internet and, besides, I had other problems of lack of voice, "pois" that can not be seen, etc.
I have returned to the maps copied from 2013, which I think are copies of Volvo originals.
The pois are seen, the voices work, but I have the problem of forgetting preferences that I have always had.
My question is: Has anyone with this memory failure problem been able to solve it with the original Volvo DVDs?
Do these original Volvo DVDs update the unit's firmware? What is the latest firmware currently?
