I need to order the cable. The plug on the CRE is the same as a mini USB cable. I have several mini USB cables so I wanted to make sure they wouldn't work before spending $25 on another one. I plugged it into the radio and the computer. The computer didn't recognize it. So looks like I'll be buying a cable.
The mobile radio store emailed me and told me that he's getting a shipment of cables for the 8900 in after the first of January.
