Last car show of the year is over and with high Covid no more until things get better here in SW Florida. I bought a W 000 589 88 63 00 set of MB removal tools. The current radio is a Sony CDX-GT200 which is apparently after market or from LTV. I insert the two keys and there isn't any "CLICK" - doesn't matter which way I put them in - they're just loose. Do I have the proper tool for an early 2006 Sprinter? Any thought on how I should remove this?
