HD Radio is the only way to go
I want to weigh in on the radio issue. I tried several USB solutions and none of them are satisfactory for automobile use. You will not get a good signal, even when connected properly to the car's antenna. Let me repeat, you will not get a good signal.
The HD Radio solution is the way to go. With a Visteon automobile radio kit (or similar), Mitch's software driver, and the proper frontend (Road Runner) and supporting skin (Digital FX 4.0), you will have an excellent solution. Everything else is BS, do not waste your time or money, unless you do not want to listen to someone you do not even know :lol:
Do some more searching on these subjects, as most have been answered elsewhere in the forum.
