Radio Conversion

[Big Blue 72]

I want to convert my ORIGINAL 1972 radio to have modern functions....bluetooth, FM, etc. There's sites I've found but controlling the radio is a confusing mix of clicking knobs quickly back and forth and I'd think it'd be hard to keep track on how to do what, and what mode you're in once you've clicked the volume knob on back and forth three times, or whatever is needed.

Does anyone have a good recommendation for a quality conversion that keeps the original look without all the mess of confusing steps needed to change modes?
