I just installed the GEX-P20HD and I'm not too happy with it. The biggest issue is no pre-set descriptions and switching back and forth from AM/FM. To get back to AM you have to page throught the FM's to get to the AM. Before digitial I could switch Back and forth. I'm thinking about taking the HD module out and either going back to the AM/FM or to Sirius. Don't like to pay for the monthly subscriptions though. I will give it couple of days working with it before I decide. Still learning about digital radio, hope I don't find more about it I don't like.
