Wondering if anyone knows where I can order a replacement laser for my nav, 2005 tsx. I have subs in my trunk wich sit directly below the nav dvd unit. This is the second time that my nav has gotten screwy. The first time I was still under warranty and the dealership replaced my dvd reader free. I think what is happening is the vibration from the subs are weakening the laser in the dvd drive. I am sure that alpine uses standard parts because I have replaced lasers in other products such as my xbox 360. Has anyone else come across this problem? My nav will only read the dvd once and a while. I never know if it will work or not. It got progressivly worse and worse and I know that when it is cold in the winter it will not read it at all. Part number for the laser maybe? Place to order one?
