Radio and nave not working after battery change

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your ES350. If your radio, navigation system, and backup camera are not working after a battery change, it could be due to a few reasons. First, the system may need to be reset. Try disconnecting the battery again for about 10-15 minutes, then reconnecting it. This can sometimes reset the electronics. If that doesn't work, check the fuses related to the radio and navigation system, as a blown fuse could be the issue. Refer to your owner's manual for the location of the fuse box and the specific fuses you need to check. If the problem persists, there could be a more complex issue with the vehicle's electronics or wiring that may require a professional diagnosis. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
