Is there a plug-in USB type radio receiver then?
Just thought I'd pitch another query; I am going to run without a headunit altogether so to receive radio stations I'll need a radiotuner card, are these available on their own or will I need to buy a TV Tuner card? If so, do they all come with radio capability aswell? Any recommendations on brand/type?
I'd run a quick search on the forums for this as I know it's been covered a number of times. Basically, you'll want to run a search for this so you can read about how most all of these solutions DON'T work.
The best option is to go with HD radio. Mitch sells a cable solution for this.
I'd run a search on that if you're interested in it!
