hi, ive got the BMW sat nav prep on my new to me gs1250. I'm looking to be able to hook my iPhone 11 for sat nav purposes. I've been told about an adapter, does it charge the phone wirelessly or do I need to connect a usb to the adapter or does I take the power from the bmw sat nav prep and a case to push my phone in and I'm away. any cheap adapters that aren't expensive genuine that people have used? or peoples opinion these carpurides as an alternative. Any advise be appreciated, cheers
