New radio for Volkswagen Beetle

I have recently gotten a 2001 vw beetle. Mechanically it is in great condition, but cosmetically… Just horrible. I'm wanting a new radio, but having all my music on my iPhone I would LOVE one with an aux port or USB. The only issue is that the space to fit a new radio is extremely skinny and oval. I know they make the spacer type thing to fit between the new radio and the hole, but I have not seen a radio that is skinny enough to fit.

If you have any help for me a would greatly appreciate it!
I also am looking into new speakers also since the ones now are blown. I would like something that hits hard and sounds good. Any suggestions are appreciated.
