Thanks Dave for your input, Funny thing is, the all the interior lights are now functioning, go figure. When I failed to find any blown fuses, I reported back to third party refurbished hybrid battery installer. They were at a loss and weren't interested in sending their tech back to resolve the issue. They said "go to the dealership" we will stand behind our work. The dealership confirmed (after a $180 diagnostic fee) there is power to the radio and no ground issues. It is indeed dead. Quote from dealer, $2910.00 for a new radio + lcd screen. No refurbished unit in their back stock. So this company is on the hook for $3090.00, if they honor their service. I'm not going to expect them to pay for a brand new radio to replace a ten year old one but I do expect to be reimbursed for the dealer diagnosis fee, the cost of a used unit and installation fee. Jury is still out as I fight that battle. Just a tip for those replacing a broken radio, there is a number below the volume control to left, for me its a 6 digits. This should match replacement unit or risk non compatibility issues. Gil & Dafo, I did find that fuses associated with radio functions do indeed control other electronics such as the back up lights and exterior door lock touch sensor.

Garec, I find your post very interesting. I own a 2014 ES300h. (311k on original battery) Just had the hybrid battery replaced with a refurbished Lexus battery ($2500), crazy thing is now I've lost all functionality of the radio, satellite radio, nav, backup camera, bluetooth ect. and the screen is dead. HVAC still working. The dome light doesn't work when door opens either, although the dome light can still be turned on with the ceiling mounted buttons. The floor lights do function when the door is opened as do the exterior courtesy lights and all interior lights when I approach. Myself and the 3rd party installer I hired thought it was a fuse thing. Connecting the battery somehow caused a fuse to blow. I've check all the fuses, engine compartment and driver foot well but all fuses seem fine. Now I hear there's this anti-theft feature that when the vehicle logs a power disconnect, the radio system and all functions associated shut down. I'm reading conflicting messages about this this code, that it applies to older cars, not gen6 ES300h's and newer. At any rate, even if I had a code, I get no prompt from the nav screen when I power up, it's MIA. If I did get a prompt, how do I enter a numarical code without a key pad. If this said code needs to be added via the APP, I can't do that because Lexus has abandoned to old APP and my car is not compilable with the new version, or so I'm told by in APP support rep. I'd love to hear if anyone has any solutions before I fight with the installer or go back to my dealership and pay them to 'enter a code'. IMG_0654.heic

2014 ES300h. (311k on original battery) Just had the hybrid battery replaced and now the dome light doesn't work when door opens. The dome light can still be turned on with the ceiling mounted switch though. the floor lights do function when the door is opened. Crazy thing is, just like you, Ive lost all functionality of the radio, nav, backup camera, bluetooth and the screen is dead. HVAC still working. Could this relate to your dome light issue? What fuse number controls the doom light? engine bay or interior fuse box? Dafo, any ideas? I've heard there is a anti-theft feature that when the vehicle logs a power disconnect, the radio system and functions associated shuts down. Could this also be the issue with your car since your battery drained sitting too long?
