Does anyone know of a setting for how long the reverse camera stays on after you shift out of reverse?

The unit is an Xtron PB7839BP in an 02 530i manual. The camera cuts off almost instantly and I would really like to have a slight delay if possible.

If it isn't possible with settings in the xtron would you think possibly wiring in a capacitor in line for the camera could accomplish this?

Also on my drive to work today I noticed the radio cutting in and out, its overcast and rainy so may just be weather related but I hadn't noticed this before. Anyone else experience anything similar?

Thanks!

It is not possible that wiring in a capacitor in line for the camera could accomplish what you want.

Thanks for the reply, I was hoping it could be something simple but I guess not.

I have never used an Xtrons head unit but if no setting exists to keep the reverse camera display on for a certain period after shifting out of reverse, then you may be able to use an automotive time delay relay.

All reverse camera setups determine if the car is in reverse gear using a signal from the car. It would be a simple matter of wiring in a time delay relay using this same signal as the relay trigger. The adjustable time setting would cause the relay to output a signal to the head unit for the duration of time that the car is in reverse plus the delay time set on the relay.


Regarding the radio cutting out, is this using a standalone antenna that came with the head unit or the stock E39 ones?

I had no idea about time delay relays, those are amazing and thats a great idea!

The radio is using the stock e39 antenna. I did notice it again today on my drive in but decided to switch radio stations. I believe it may only be happening on the on particular station. It only drops out for a second but I'll compare some other stations on my drive and see if it happens again.

What's the deal with glare on the screen with the Xtrons units?

I installed mine and I'm please with the performance (thanks to this forum). There was a shipping protector on the screen with a white sticker attached to the corner so I peeled that off. In bright sun, I can't see anything on the screen. On close inspection, it looks like there is a secondary screen protector still in place because I can see what appears to be a spec of dust caught behind it. Can anyone confirm that this is a second screen protector? If so, can it be peeled off to reduce the glare?

Mine came with a 2 layer screen protection as well... The first layer (with the white sticker) is only meant to help not scratch the main screen protector below it, during install of the screen protector, while using a squeegee to remove any bubbles. Then, I'm sure they just leave it on there for an added layer of protection while shipping. I personally, very carefully, removed the white sticker on the first layer and I'm still rolling with that. Then I figured when the first layer gets scratched up enough, I could just remove it and still have the original screen protector.

So, I can't say much for how the glare is on the second layer or on the screen itself but I don't seem to have too many issues with the first layer. I would almost think it might be worse with just the screen as it's glass and will reflect quite well. But, thankfully, these days we get to run with capacitive touch screens (same screens as on smart phones and tablets) and they are soooooooo much better than the old resistive touch screens in how much clearer everything is and that the screens are optically bonded with the touch screen and don't allow for any air gap between the screens, producing a much less glaring screen.

You could also just remove the stock screen protector and replace it with an anti-glare screen protector for a 7" screen or tablet and could trim it to fit if needed too, but it will degrade some of the clarity of the screen... Where as the crystal clear ones, tend to glare more and show more fingerprints. There is no perfect solution as far as I know; i.e. Crystal clear + No glare + No fingerprints... Although I'm pretty happy with the first layer with the sticker removed... Seems to have a nice balance of all 3.
