Can cot connect to RNS510 of my VW Passat. Everything was working great. Until my wife could not connect via bluetooth with her iPhone 11. My own iPhone 12 Pro was working fine. Until i did a factory reset of the VW carkit. Then my iPhone could not connect anymote. In the pairing mode i try to put in the code that is presented on my dashboard. (16-digits like 1111222233334444). Then ik get a 'log-in' failure on my dashboard. The strange thing is that paring my iPhone as Multimedia device is no problem. Both iPhones are on IOS 15.0.2.
