My Subaru does this (radio shutoff when cranking the engine) and I always figured it was for the reason Diesel_Dave posted above. Interesting that your circuit worked. I'm annoyed by the 3-5 seconds it takes for my Subaru (Clarion) radio to re-boot after an engine re-start but not annoyed enough, yet, to try a fix. Maybe later. Good work.
Oh, meant to mention that maybe you'd want a current limiting resistor between D2 and C1 to limit in-rush current when you first charge C1 but, heck, if it works and doesn't blow Fuse F1 then ... far out!
