Frequently asked questions
Anything else? Write to Keno directly.
Will the radio fit my car?
Yes, if your BMW has a DIN radio slot. All radios fit all older BMWs, for example E28, E30, E31, E32, E34, E36 and more. You can always get the right connector, and on BMWs from the 90s on, the original connector is already the correct one.
Am I buying a radio or a conversion?
With the conversion, you send in your own radio. A complete radio is a unit that has already been converted.
Is hands-free always included?
No. Choose the hands-free variant if you want to make calls, and check which microphone you need. It is also available separately for E31, E32, E34 and E36.
How long does a conversion take?
That depends on the work involved and the current workload. Ask for the current processing time before sending in your radio.
How do I order?
Choose a product, check the variant and add it to your cart. For the conversion service, you then send in your radio.
Hi, I’m Keno.
I develop the boards and software myself and convert every radio personally. My goal: new features that feel as natural to use as the original.
