I got free FM Radio (Thanks to Mick300ZX) and since some dont have time, I figured I would document exactly what I did. (Bored at work)

1. Go to car and write down all your pre-set stations
2. Go to computer, go to this link:
http://www.htcfuze.org/third-party-touch-pro-software-rss/master-application-thread/
3. Scroll down to Mick300ZX post and download FM Radio to your computer.
4. Sync Phone,
5. Open Explorer on computer and find FM RADIO.COM. Right click and "Copy"
6. Open Explorer in ActiveSync box, click mobile phone, then storage card.
7. Right click, then "Paste"
8. Remove phone, on phone, start> Programs> Tools> and click on FM Radio.CAB and install as usual
9. Plug in adapter, back to the Program tab and click on the radio icon.

Now the fun:

It will immediately do a scan. Click on the < or > until you find the station in your pre-sets.
While playing the station, tap preset in lower left of screen. tab up to the first preset, lower right click menu, then set.

Repeat except for the next station when you go into presets, tab up to second preset and so forth.

Enjoy your day at work!!

Takes no battery at all, and if you get a call the radio cuts off. When you hang up, back to your station!
