kinda lost on what to do with this problem I bought a 04 with navi and when I bought the car the navigation screen was broken obviously it was punched by previous owner for some reason anyways when I bought the car the stereo worked just fine and the navigation screen would still turn on but would go black after a few second and the climate control screen would fade in and out seemed to stay on longer in colder weather. but recently the stereo does not work and navi screen doesn't turn on at all and the climate control screen doesn't come on at all either. now I was going to spend about 500 bucks on new/used radio,navi,climatcontrol screen but I don't want to waste that kind of money if its just a fuse or electrical problem has anyone ever had this issue with their tl and know where to start to try and diagnose this problem... and it does look like the dash area has been touched in the past some panels are not lined up properly any help is much appreciated thanks
