I couldn't find a definitive video or explanation on YouTube on how to change the interior light bulbs in the car. Apologies if this has been done to death but I couldn't find an explanation on getting to the bulbs. All the bulbs I found below were 12v8w w5w type bulbs. Sunshade mirror vanity lights. Left edge with a nail file or fine screwdriver to push the clip before pulling out the grey assembly with the bulb. Bulb is facing sideways. Pull out bulb and replace. This seemed to be the only one needing the grey assembly to be pulled out. Central lights between sunshades. Prise off the clear plastic starting from the top. You'll see the silhouette on the edge where the plastic holds onto the plastic. Bulb facing you. Pull out and replace. Light next to 2nd row and third row seats. Prise off the clear light reflector from the top using a fine screwdriver or flat spectacles screwdriver. Bulb faces you. Pull out and replace.

I have encountered this. Very flaky and a car wash destroyed the roof paint, requiring a respray. Light hand-wash every now and then seems to be the best thing for it.

I took a picture but in all honesty I may not have grabbed the wiring that was deeper inside, so may need to snap another better picture. No canbus on my headunit, just a generic set of connectors as seen on many. The picture below is from the one that was playing up, replacement just had a few more additional connectors for 4G. Steering wheel controls worked. Interesting to see the amount of space under the seat. Kind of looks like I could squeeze a diesel heater there.

More investigation.. Piecing together the capability of this car and I suspect it has a screen mounted on the roof. I can't be sure as its flush and may just be a blanking plate. I'll try and post an image.

As the car had a replacement Android head unit in the ATH20 that wasn't working, I proceeded to swap it for one I had with carplay and looked around to see how it tapped into the speakers. Based on the info from this forum, I counted 17 speakers and a subwoofer under the drivers seat. I see the android head unit plug containing the speaker lines connected to a brown connector which I assume is part of a bypass cable leading to the area under the passenger seat. I haven't gone around testing what speakers emit sound although I have read the subwoofer is not used. I'm curious how the 18 speakers were used in the oem and whether the subwoofer can be reused or connected to the subwoofer output of the Android headunit. I see aliexpress sell large head units. Would these use the full 18 speakers?

Greetings, I feel like I have come full circle, RAV4 20 years ago and now back to Toyota Alphard. Lets see what tweaks I can make with the extra space eh. My days of plastering the frame with sound deadener are most definately over though.
