The real question is: where do you live? If you're in the USA, then
a new HD Radio may be right for you.

Scan through fleabay for Visteon or Directed brand HD radio units. Both are
modules that have a separate LCD control panel. They've got both FM
modulated and audio line-level output. You can feed the FM signal into your
existing FM radio setup. Or use an AUX-in line if you've got an amp setup
and want the 'better' HD sound levels.

The upside is it's also capable of continuing to act as a regular radio.
It'll tune to AM and FM, along with HD stations. This means you can set it
up with the LCD controller in perhaps a more convenient location than a
current radio. Put the control box anywhere along the FM antenna cabling
and the LCD controller likewise anywhere within reach of it's cable (or an
extension).

Both are also popular with the computer geek crowd as the LCD panel can be
replaced with an RS-232 adapter to control it from a computer.
