I suggest you try something different:
I use a Parrot product, their model #3100. Parrot makes bluetooth units that immediately updates our phone systems to modern use.
I have multiple cars and they all work perfectly with my one I-Phone. They all sync up to it automatically, they all work through the wiring that already exists in our cars. The system automatically mutes the radio and it even shows 'PHONE' when in use, just like the analog system.
It really mates the best of both the existing wiring/system, including the use of the 2 dashboard speakers that ONLY work for the phone system. Bonus: It frees up the hand set space and head set space for something else, like storage.
Of course, to keep your car in 'original' condition, keep the old analog equipment, so if you ever want to 'show' your car in the year 2025, you can claim it fully original.
