Have Toyota Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.working after noon till just after midnight.
The battery that was in the vehicle was it weak or did it go 100% dead?
When a battery dies it rapidly pulses the remaining voltage on and off till dead. This results in power surges to sensitive electronics. A radio failure after a dead battery is quiet common. I suggest you attempt a reset prior to radio replacement. Remove both battery cables, hold them together for 1 minute then 30 minutes later reconnect them to the battery and test.
