🤣 lol

thats a negative.

when did you buy this truck? what all have you done to it maintaince wise so far?

if the radio is stock it may not have been at one point in time and the wiring could be screwy somewhere along the line…I would check the connections and if theya re all fgood, follow the lines. I had similiar probelms w/ my blazer and it was bc some retard tried to put in his own system and fried the lines so the dealer just threw in a stock radio.
