i bought a 05 LR3 and the radio is not working. I bought an aftermarket radio and install kit. i installed everything and found that i dont have power to the red wire. i dont have any power to the head unit and the power button does nothing. I got onto some forums and found some information about troubleshooting. I checked all my fuses and verified i have power at the amp and the fiber loop is putting out light but im not getting anything at the head unit. Do i need a new amp? does anyone have any other information pertaining to troubleshooting this issue. Any help would be appreciated. Thanks
