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.
