Got the dreaded error3 code alrite, tried taking it out (worked before) but the CD got stuck, after taking the CD player outta the car and having a go at taking the back of it off now to get at the CD changer and hopefully take out the CD without making s@3! of it!
I was doing exact same thing with my one and error code was there all the time, so I stripped it down (hammer time!) and just got the alpine instead! Check do You have build-in amp if so I have lead to bypass it (never used) to connect new radio, just in case..
