My son in law has a 2016 GX460. Battery died when my daughter was out and about. she had it jump started then went home and my son in law installed a replacement new battery. Now the radio and nav is not working. at first the ac wasn't working at all also. we read some on line and this seems to be a common problem with lexus. We checked all fuses and tried disconnecting the battery, all hints and tips we could muster. Now the ac seems to work but still not radio/nav. camera displays when in reverse. Any additional info or suggestions would be very welcome and helpful. Thank you in advance if you can help please.
