My 1986 420 SL (type 107) has a Blaupunkt Boston SQM23 radio/cassette player fitted. Looks like it was fitted originally. Unfortunately it is no longer working. So, I want to buy a replacement, but not a new radio/cassette, rather one in keeping with a vehicle of this age.
My question is this - how do I know what replacements will fit? For example, I have seen a Blaupunkt Heilbronn SQM 39 that might do the trick and a Blaupunkt Hamburg SQM 23. But how do I know that they can fit where the Boston used to fit? Does the fact that mine is a "23" and one of the potential replacements is a "23" help, or is that a red-herring? Does anyone know how to get information about old Blaupunkt radios, when they were manufactured, which were used in SLs in the eighties, and what is a suitable replacement for a Boston SQM23?
Any leads or thoughts much appreciated.
Many thanks, in advance.
