looking at redoing a 1966 beaumont radio anyone got a recommendations maybe up grade to blue tooth?

I recently put a Panosonic bluetooth radio in my Hyundai Accent 2012 model.

The digital display  can only be read in the underground garage otherwise completely unreadable in bright sunlight. I have one fm  station tuned in and primary use is for using phone calls. Nice feature to answer and end calls

Mostly hands free.
