Whats going on Tundra Talk world? I installed an aftermarket HU Alpine IVA-W505 and everything seemed to work after i buttoned everything back up. I didn't figure out until it was dark that I had a problem. I turned on my headlights and all of the lights that illuminate the A/C controls and the gearshift position indicator n longer work. In addition the clock also disappears, very strange I know when the head lights are off the clock works but when i turn them on it doesn't. I searched the forum and all i found is that i may have blown the rheostat. I called my local Toyota service dept and they said that it would be really hard to do that being that everything works except for the lights that I stated above. Can someone please help me?
