Truck has 280,000km on it my question is how does the rasio effect your insturment cluster as soon as I pull the radio plug adapter out for adding a cd player it kills the power to the insturment cluster as soon as I plug it back in I get Power back but when power is back takes a few seconds for the gauges to come alive they jump all over the place then go back to accurater reading. cd player has no memory and will not pick up any local radio staions and att is pluged in I also have had this deck in before had no problems till now

check the ground on the upper left kick panel as the ip and radio both ground there then clean your battery terminals as you may not have a good ground. Other than thathave a radio guy look at it.
