I have 2003.5 Sedan, with the ugly dirt color radio trim.
my cd player died and trying to figure out what a "cheap" fix..
I have a factory NAV.

So I figure I could just get a $500 DD player.

I need to buy the JDM trim, that's it correct?DOMO

 

You need to get the A/C control and the finisher.

All the parts needed are there.

 

A cheap fix will be to get a used OEM unit and install it or send your radio out to get fixed.
