He may have to get underneath the dashboard and see if their is a security strap or wire harness holding the radio into the mounting sleeve. It's common for installers to strap down the stereo to prevent thefts and other installer from easily taking the radio out. Have him keep trying.

You may have a bad volume down switch. If so, it needs to be replaced.

When a head unit doesn't remember settings like yours, then the Yellow constant battery wire isn't hooked up correctly. This wire provides power to your unit constantly from the battery so that it can remember the settings and such. Your aerial not going up is the Blue power antenna wire. This wire will provide power so that when you turn your unit on, it powers the antenna to go up. Hope this helps!
