Garmin 530 Rhino????
No you can't Breaker Breaker....
The Garmin 530 Rhino is a FMS/GMRS radio.
Looked at the Garmin Website for this radio and the spec sheet states its a FRS and GMRS radio with 22 channels. That is standard FMS & GMRS. It doesnt say anything about being CB frequency capable. Reason I'm chiming in is because I too am looking for a good hand held CB. I've already got a good Midland FRS/GMRS radio and you gotto be careful with those, because if you use the GMRS channels you need a FCC License.
