Thanks yeah me too. Nope that's the whole reason I took it off to begin with was to try and find a leak in there. And you really can't see much under there anyway. There is like a big steel compartment welded to the firewall under there can't see jack under it.


I know it sounds bad but you might have to pull the windshield. my obs was like that, never could find it. but the windshield was cracked when I got it, so I had it changed. few years later I found a leak, searched and searched under the passengers side dash for it. never found it. we had a small hurricane go thru Nola and it finally rained hard enough it was wet up at the head liner.
it was life time on the windshield, so I had them pull it and last guy hadn't sealed it well or something. had to grind down some rust, prime the area and put the windshield back.

that finally fixed it.

How is it sound wise with the bose setup
The sound is very good until you really push it, better than stock. The stock speakers are not the best.

There is a "32 band equalizer" that seems to work to adjust to taste.

I'll see if I can get a video up later this week, I'll go through the setting and stuff - I have never posted anything on YouTube before. If there is something you want to see, let me know.

Also, the product page says that it wont work with the CD and DVD slot radio - this is untrue (it's what I had). It just won't work with the white plug stereos without some kind of adapter.

Edited***

The unit is basically an Android tablet with an amp and plugs. It runs carplay "on top" of the interface like an app. There are also tons of RCA in's/out's on the unit. I may add a sub amp or something down the line - but it is good enough for me as is in reality.

I went for one of the more "expensive" units. It was originally grouped with 2 other models on Amazon - the other 2 had knobs. I was going to buy a knobbed one but realized I haven't used a DVD or CD in 20 years or so.

There are buttons on the bottom but I use the steering wheel controls mostly. Everything is included but it may need something for the rear screen if you have one. I didn't bother hooking it up.

It has carplay for apple that works great - wireless. I was also able to download Netflix, YouTube TV and Amazon Prime to the unit and stream from my driveway. I am sure you can tether to your phone n the road if you want to watch tv and kill someone.

I cut the supplied harness's reverse line as I have the camera in the mirror. In my setup, the screen would go black in reverse with the unit, now it just stays as a normal screen (the mirror still works).

The sound was way loud at first - I had to go in the factory settings using code "0000" and tell the unit that I had an amplifier and adjusted the "gain". I didn't even end up using any of the 3 USB ports - just wireless. So, install took less than an hour in total. Simple plug and play.


Edited****
CarPlay is what apple uses for texts, calls, navigation, music apps. There is no web browser. The unit itself has chrome installed.
My system has the standard Bose amp - the unit integrated with it. Fade/balance works as you would expect.

I am assuming it uses your phone wifi for the chrome browser? Does it have it's own GPS antennae?

What do you think? @PG01 says he had this problem. @swathdiver said he sealed his. I did a test dab of silicone sealant to see what happens.

Think all of our fins have that cracked gasket, definitely seems like water would seep in there, especially if parked downhill.
Although I would expect some headliner stains, but maybe it drips along the wire or underside of roof...
I had a headliner stain when the rear liftgate wiring boot popped loose, luckily it cleaned right up...
