Checked voltage to aerial amp and only getting 0.78 volts,therefore i will have to find the problem here as i would think it should be 12 v,correct??
Also if the aerial amp is down am i right in thinking that i would still get a signal all be it weak,but at least enough to give poor radio reception?

Hmmm... thats a clue....
Here's a thought: if the power feed to the antenna amp is shorted (inside the antenna amp, or connected to wrong antenna amp plug) then the radio may switch to automatic protection mode, and switch off the audio output stages. Maybe...just maybe... this is the problem
So try this to find out if I am right:
1. Unplug the white wire to the aerial amp (which is the power feed from the radio).
2. Observe what happens with the radio - check if you have CD & nav sound. If so, your white wire to the radio is connected to the wrong plug on the antenna amp, or the antenna amp is faulty.
Let me know what happens...
