I bought a 91 trofeo yesterday. Its if fairly good shape with no dents and little rust. The main issue i want to fix is the vic doesnt work. I can use all the hard buttons but the screen is black. I guess what im wondering is if kt could be something i could fix myself. Im pretty technologically inclined. And if i cant maybe i can just install an aftermarket radio. The only problem i see with that is i would be losing all of the climate control buttons. Thanks in advance for any advice
