    My model is CL203 C-Class 2005. Looking for connection in between a car and a radio. Radio model is MF2530. Could you please suggest anything for me? Is this item will help? Thank you

    Thanks for your question.

    The item you have shown is just an ISO adapter, which is fine if you can confidently run a separate ignition and illumination. If you have steering control they will no longer work with that ISO adapter.

    I have shown a CAN-BUS adapter which will keep your steering control (you will just need a patch lead depending on what head-unit you are installing), this will also supply an ignition feed, illumination, speed-pulse, hand brake, reverse signal.
