Re: Time for a new headunit?
It could be a loose/weak ground or connection for the ignition wire. I went through this with a touch screen Pioneer. It would randomly cut out & then come back on. There was something in the vehicle harness probably caused by the previous owner. Ended up being the wire they ran for the ignition/switched source. Bypassed the harness completely & no more worries. We first ran a constant straight from the battery, then a new ground outside of the vehicle harness & then finally the ignition wire. We wired it to the constant with a toggle switch. It could also be a loose soldering point inside the radio.
