Question about Alpine CDM-7834
I got an alpine cdm-7834 that i had in a 96 yukon, everything worked fine. i had another stereo installed into my yukon and put the cdm-7834 in my dads 95 ford f-250, now it comes up with the nubers and everything on the stereo but it has no backlight and is really hard to see. what could be the problem?
The only possible installation problem could be the illumination wire on the head unit. If this is hooked to a 12 lead it would dim the backlight. Try disconnecting the orange wire if it has one(I'm not sure if the 7834 had a dimmer lead). If that doesn't fix it the head unit will have to be serviced.
