SL/R129: Raido
The "pop out screen" is too low and distracting so I am not a fan but the new systems that come up out of the dash and are at eye level may be a winner, but not certain if Acura,s system can be put in the phone keypad area.
I had Radioman in CA rebuild the bose amp system and that was the best improvement for the entire audio system. The speakers were cracklily and static at times. That noise progressed to a hum then no sound from one or several speakers.
I would buy a single DIN head unit with bluetooth and XM. In Kansas the HD radio is not a factor but maybe for FL. I have kept all the becker stuff for the next owner or restoration if I get to it!
Having an antenna control signal is essential as it is used to wake-up the BOSE amp and the CD-changer, not just signal the antenna to run up/down ...
