1990 ZR-1 Aftermarket Radio not working - ZR-1 Net Registry Forums

Hello guys! I am deeply honored to finally be able to own a Corvette. I am from Athens, Greece and I just got my 1990 ZR-1.

I am in desperate need of your precious help.

The car already has an aftermarket stereo with an amp and subwoofer etc so previous owners probably bypassed the BOSE?
I tried replacing the old aftermarket head unit with a Pioneer bluetooth one.
I joined the wires and it fired right up. Sadly however, before I taped my connections I started looking on how to connect the RCA from the amp and the wires probably moved and touched one another and suddenly the radio stopped working. I checked the fuse on the Pioneer headunit and replaced that and nothing. I checked the fuses on the passenger door and all seemed fine.
The antenna does not go up.
I did not check the small fusebox under the passenger side dash.
The radio itself is fine because I took it to the shop I got it from and they tested it.

Another ZR-1 owner told me that it is not the CDM since I have climate and dash gauges etc, everything else works.
Could you point me to the right direction?
