Default Same here.

Once pulling the fuse didn't work though. Dealer said that there is a fuse in the back of the radio that blew.

I tried pulling the fuse out of the back of the stereo out and waited 10 secs and no luck. do i need to pull the fuse out of the fuse panel for 10secs. what fuse it is?

Default Pull the one out of the dash.

If that doesn't do it, you probably need a new head unit.

Default Re: Pull the one out of the dash.

Ok, i pulled the one out of the dash with many different scenarios (radio off, car off, radio on, car on, etc) and no luck.
when i put the fuse back in the radio display gets bright red and then back to normal color red but still nothing is displayed. just a blank red screen.
i wonder if my radio is broken. i checked all the fuses and none are bad.

Default Yeah, chances are it is.

I have had a couple that wouldn't work and ended up replacing the radio.

Default replacing the radio

when you replaced the radio did you have to get a new amp? i have thought about replacing the radio but i am afraid that i will not be able to use all the speakers and that i may have to get a new amp. let me know what needs to be done in order to replace the radio. thank you,
scott

Default You'll have to do some research if you're going aftermarket.

I am a dealer tech, so the factory stuff is just plug and play.
