The Mobis Lowline has your standard ISO connections on the back, nothing strange here.However, smart don’t really know what all of the connections do. In fact, there was nothing to suggest there was anything else to know about the stereo until I took a Lowline stereo apart and found this.
Clearly there is more going on here than we realised so I traced the connections and created a table.

All of the connections listed on the circuit board are shown in orange.
CAN Bus high and low do not seem to go to the rear connections.
Pre-Amplified Outputs?
No pre-amplified outputs are available on the rear of the stereo but I believe I have found the left and right output pins before they enter into the amplifier. This is my best guess and not necessarily correct.
If you want to attempt to wire these 2 connections to a pair of unused pins you can then use any of the ground connections as an audio ground in an attempt to create a stereo low level output. It’s not something I have tested yet but if you do, let me know how you get on.
Aux In, Nav-In, Telephone Microphone! How?
That’s a simple one to answer but not such a simple one to prove. Somewhere, there will be a hidden menu. Other Hyundai Mobis stereos have hidden menus that can be accessed by holding down 2 buttons. I have tried some combinations with no joy. Look here for a Mobis stereo hidden menu example.
Who Are Mobis?
Hyundai Mobis create OEM stereos for various manufacturers. I hadn’t actually inspected one of these Lowline stereos until late 2014 so assumed that they were also made by Bosch. I was wrong. Mobis stepped in and created replicas of the stereos originally made by Becker.
