My monitor came with a 12v cigarette lighter power cable, so I bought one of those 12v cig lighters terminated in a red +12v and a black negative, so you can tap into a power source. I did this because this monitor was actually my 2nd RMA due to a power circuit failure, and I didn't wanna tap directly into a power line, due to fears of it breaking again. Don't fix what isn't broken.

HD Radio is pretty awesome, and for sure a great addition to a CarPC setup. The one I have, the Visteon HDRadio Tuner, I got from:

Amazon.com: HD Radio¿ Component Car Tuner Kit: Car Electronics

Unfortunately, I see that it went back up to the correct market price. I bought it when it was only $30 bucks, it was nice. But in any case, the HDRadio works awesome for being a radio. When connected to HD, it sounds very clear and the frequency response from all levels is great. The only time it becomes weird is when it frequently hands off from HD to StandardFM. However, this only happens once a blue moon, and it's no big deal.
