thanks for the tip. Meanwhile the radio is working again. I have deleted the HERE-software and use the 9.6.29 IGO-Software now, which seems to work perfectly.

When looking for the IGO-Software in the internet I came about an article that described the possibility that in other Cina RNS one could see the arrows of the IGO-navigation in the MFA-screen (white) of VW/Skoda. Is that also possible with my Pumpkin Radio and if so, do I need a special version of IGO or special entries in the sys.txt of the navigation software to see the arrows in my MFA-display?
Another question: Is it possible to change the display time for the climate controls, when I change them?
Best regards and have a good start into the week!
