The O5 control head does not have a color display it has different backlighting colors such as red, orange, green, and custom. The only color heads are made for the APX which will work on the XTL such as the O3, O6*, O7, and the big daddy O9. There are also one or two more for harsh environments.
It's not my intention to put you down. I just noticed that this is only your second post. You should know that the members here require correct and detailed information.
If you have any questions in regards to reading the flashcode, firmware version, host, and rather the radio has encryption installed. Just send me a PM and I can walk you through getting into test mode so you can get the info direct from the O5 display
So in closing welcome to ELB and I wish you the best of luck.
