Hello, I have resolved the issue.
I purchased a pre-owned item from the online marketplace eBay, but, I had difficulties in programming it to align with the vehicle's specifications.
As a last recourse, I initiated communication with MB in order to request a code; nevertheless, their assistance proved to be unproductive.
Subsequently, I inquired about the procurement of a substitute component from the authorised dealership of MB.
The quoted price was £2800 plus value-added tax (VAT). Ultimately, I chose to proceed with the conversion kit that was previously shown in this discussion.
The pioneer SPH-DA230DAB has been successfully installed and is functioning excellently.
The kit has a superior fit that surpasses first expectations, while also presenting a refined and aesthetically pleasing appearance.
The whole cost of the bill amounted to £620. Given that this was the only viable choice, I am rather content with the outcome. Additionally, I now own DAB radio and Android car play navigation features.
The process of finding help online has proven to be challenging and frustrating.
