I installed a r/s with keyless and trunk on a 04 pontiac grand am. Now the radio display is dead. The radio works fine but there is no display. Has anyone had this happen or is this just a really wierd coincidence.btw the radio was never dis connected from the car. thanks.

Also, the 04 pontiac grand am is known to have Display problems. I have seen..... Just unplugging it causes the same problem. We repair them often

I've actually seen GM radios(especially pontiacs) from 96-present have display issues. My moms was one of them.

I used a omega DB-PASS-23 hooked to the databus plug under the dash. Any chance this can be fixed?

Should have GM warranty on Radio......Have Dealer check it

display problems were common on pre-200 Pontiac radios that used a single lamp in the display... 2000-up radios have 3 separate AVR circuits with 3 separate lamps in the LCD display.... the chance of all 3 going out at the exact same time is pretty darn coincidental..... as an AC Delco radio repair center we service lots of these units for partial display failure, but i dont think i've seen one yet where they all went out.....

That is how I have seen at least 4 in the past year...."coincidental"

We do MOPAR, FORD & Delco warranty...........GM is the all most as bad as Ford

I think GM has a Static Discharge Problem

So this radio needs a trip to the dealer for repair?

If it has Warranty it is worth the trip .....But make sure you don't have a fuse out up front
