I purchased the following after market navigation unit. I am trying to install it on my 2012 X1. The only problem I am facing is the radio unit does not draw power from the bmw radio power harness and instead has a separate yellow wire to connect to a 12v line. What is my best option? I would imagine the power harness has a pin that is a 12v line and ideally I should tap in to that somehow. The other option is to get it from the fuse box. My goal is to have the same experience as the stock radio how it can stay powered on as long as the key is in the ignition and doesnt matter if the engine is started or not.

The seller is suggesting to connect the yellow power wire of the unit to the battery or to the fuse box. But I am not fully comfortable with that.

Any suggestion?.. I am really stuck after taking the dash apart!
