Complementary Modification:

Install aftermarket radio

The radio is located in the center of the dashboard. There are a few different radio options that came in BMW E90 models. You can swap your radio out if you have a problem using the instructions below. Always check the fuses before condemning your radio. If you want to install an aftermarket radio, use these instructions to remove your radio, then install a wiring harness adapter to the factory connector and install the aftermarket radio. I suggest always using a wiring harness adapter and avoid cutting any wires on the factory harness. This way if you want to reinstall the factory radio, it will plug in and work as it did when new.

The IHKA panel is the main control for your vehicle climate control. The panels can fail over time, losing function of one or more buttons. When this happens, your interior climate control does not function normally.

In this tech article, I will go over how to replace the radio and the IHKA panel.

First, you have to remove the dashboard trim strip.
