Does not sound true to me. I’m sure you can get power to the puck, but not sure you can get the phone to work. It may have been disconnected from the fiber optic loop, but you can check that later.
Start with the simple, like a fuse to the cradle. Search for”Fuse Map” and you’re good to go. Likely behind passenger seat. See if there is power at the fuse, and the fuse is good. Blown fuses normally mean something has a short, so it can blow again.
You may want to get a WIS (work instruction) CD off eBay and install it on a laptop.
This will give you tons of info on how to analyses systems, trace wires and trouble shoot. Only about $10.
Or if you consider this car a keeper, get an SDS and learn how to use it. Will pay for itself many times over the life of the car.
