Problem Description

I have a 2005 SLK 280 Mercedes which originally came with a hands free mobile phone, unfortunately some where along the life of my car the phone was lost, there is a connection socket for the original phone in the centre consul but it does not support my Motorola G5 which does have Blue tooth facility.

Does anyone know of a fix for this problem without having to go to the nearest Mercedes dealership which comes with a starting cost of $1,000 just for asking the question, (just joking) but you get my gist.

All the necessary hands free requirements are there, "key pad" "steering wheel buttons" "inbuilt mic" I just need to marry my phone to the car, is this possible??? without costing a fortune. ie. more that $50.00.
