Did you check with a meter or test probe that you had power at the wires before you connected them to the unit?
If not, you have the added complexity of not knowing whether it's the canbus, your connection, your GPS cradle, or your GPS.
I metered the bare wires first so I was sure I had power and correct polarity. It worked perfectly once I connected it.
A little more information on what you know is working and what is not might be helpful.
I'm getting too old for this... Not!
