@joroartcorp I did that, but the price wasn't shown, everything was greyed out, there was no option available. I asked support team, they replied that I needed to buy a flat config which costs 129 euro. That is more expensive than getting it done at dealership. So I got it done at a dealership cheaper. I understand, probably, buying flat config gives me more opportunities, but I don't need those, the only thing I needed is changing the frequencies, which was cheaper at a dealership.
