I'll point you in the direction of this thread over here from the Motorola section:
Here are the key facts that you need to know about monitoring a TRS with your /\/\otorola radio: Programming of Motorola Radios is done with software called CPS - see the sticky in this forum for info on how to legally obtain it - it's actually quite easy; Motorola is glad to sell it to you...

Long story short, most people on here will not help you with this kind of thing and point you towards buying a scanner. The expectation of buying such a radio is that you have some knowledge, software, and cables to do such a thing without much help or assistance.
