If you have a Generation 2 Motorola radio (XPR7550, XPR5550) and you have the latest firmware (2.50.05) DO NOT clone the code plugs that are about to be posted. Doing so will delete all of the very nice voice quality upgrades that Motorola recently did. The only way to get them back is to do a recovery, and that is more complicated than needs to be covered here.
If you have a Gen 2 Motorola radio, and you have firmware 2.50.04 or older, you can clone your radio using these code plugs, and then update to 2.50.05 and get the audio settings back.
