As noted above, you might ask in the North Carolina forum whether anyone is able to use a Uniden 245 on the Charlotte system.
If they are still using the Motorola system, what you have might work. If they have migrated to the P25 system, it will be like trying to watch television with an AM radio.
The following is a link to the manual, if you don't have it. Programming instructions can be found there.

I did a search for programming software and came up empty handed. Programming software usually allows premium subscribers to "capture" data to program the scanner.
Not being insensitive to old stuff (I just got confirmation that my social security checks will start in December), but a lot of developments have occurred since the release of this scanner some 12 years ago. Those developments have rendered your scanner obsolete for the "good stuff".
If you consider a new scanner, I'd shy away from the 396XT. The new Charlotte system is a simulcast system, which is what our local system is. My 396XT has its issues with clearly decoding a simulcast system. The newer x36 scanners deal with simulcast systems significantly better.
