Radio or no radio

My DIN modified rally panel was all about the radio in both concept and goal.
It wasn't until I pulled the panel again to change the ALT gauge to a VOLTS gauge that I discovered its greatest benefit. Removing the instrument panel was so quick and easy,
i said WOW ! I was really proud of myself for a time, then i remembered that my little IVR wasn't intended to be a universal part either so I gave thanks to God for my blessings.
So I got off topic a little. What I'm saying is in some cases there is a lot more to be gained than better sound.
