    Hi Guys,

    So my headunit has stopped working (i have previously created a theread for this)..under advice from another member i checked it was getting power which i belive it is ....i was getting a reading off a number of the connections with the multimeter and i also ran an led across the connections and that lit up so i belive the unit is getting power.

    So i then bought a new HU (second hand).....still nothing happens when it is plugged in.

    So my next step is to run the headunit across the battery so see if i can get any life out of it! Does anyone have any suggestions as to which pins i need to run the power through on the back of the radio to see if it is working.

    Failing that would i be best taking the car to an auto electrician to look at?
