Pairing? I didn't have to pair my iPhone - but then I prefer to use the lightning cable to plug my iPhone in to the system, there's no pairing required you can just plug any random iPhone in and use CarPlay immediately

Is your iPhone still (bluetooth) paired with the factory head unit? If so, try to un-pair that first - it will definitely confuse things if the phone is trying to pair to two different devices at the same time.

For audio, also check the factory head unit is still set to aux output as well before switching to the Naviplus system, it's easy to miss that (or find it gets auto-switched to a different source, perhaps if your phone is still bluetooth paired to the main unit and it detects it)

Do you have the option of trying CarPlay with a cable, or is it only set up for wireless?

I have tried it plugged into the lightning connector that's when it is showing on the screen but no sound, so as you say the head unit has not switched off the car radio and should be in AUX?
I will do what you have suggested without Bluetooth, I did not turn to AUX so that may help, I think that I may have confused the system by having the Bluetooth running with the car's phone?
But why would you need to turn off the Bluetooth every time you get in the car? I thought they are two systems that are able to be switched via a button on the steering wheel.

The Naviplus system and the factory head unit are both always running all the time.
All the switch on the steering wheel does is hijack the video and touch-detection circuitry to redirect them between the two systems. Neither system is actually aware of the other, it all operates like one of those KVM switches where two computers can share the same keyboard, monitor and mouse...

Note that the switch doesn't hijack audio circuitry in a similarly invasive way, it simply plugs into the existing AUX 3.5mm jack cabling (it just taps into this circuit behind the dashboard, rather than having an unsightly cable plugging into the rear socket).

This is why the factory radio needs to be set into AUX audio mode to hear any sounds through Naviplus functionality.

I'm guessing if the iPhone has established a bluetooth connection to the factory unit first, it may not properly connect to CarPlay until Bluetooth is switched off (or the vehicle is "unpaired"), as you can't be connected to "two cars" (from the phone's point of view!) at the same time.

Personally I don't use the factory bluetooth integration as all that functionality is provided by CarPlay anyway.
Yes, there have been a few cockups where I've been listening to the factory DAB radio and answered the call on CarPlay, and then realised I need to faff about to switch from DAB to AUX audio so I can hear the caller, doh!

To avoid that I now use the Radioplayer app in CarPlay mode instead to stream radio...

Thanks for the info DJ
It would appear that I can now play from the phone but the touch screen will don't responded, so car play, Waze, work just not on fullscreen on their own?
I cannot swipe the screen to go to settings the Naviplus people say to hold the centre of the screen for 20 seconds? not working?
I have pulled the fuse to see if that will do anything I will let you know how I get on

When the tech demonstrated integration with his Android phone, did he use the touch screen for input at all? Or did he just use his phone's screen to input options?

It's possible the touch circuitry integration hasn't been installed quite right.

It's a resistive touch screen, so needs a bit of a prod (swipes are particularly unnatural on it) - but you'd have definitely seen it respond by now if it was functioning...

(I'm assuming you mean the screen image is working OK, showing Waze maps etc on the touch screen, it's just not accepting touch inputs?)

Hi, DJ what do you think about the screen that I posted?

That's looking exactly how it should! Clearly the video and audio side it working properly

You should of course now be able to press anywhere on the screen for something to happen - a quick tap on the dots in the bottom left would take you back to the home screen - a long press would invoke Siri, etc...

If there is no response to touch input, then something isn't connected correctly.

Did the technician demonstrate touch input on the screen?

Hi Mate what you are saying and what I am thinking are the same, it all points to the installation.
The problem I now have is to have a fight with the installer or strip it out myself (as I should have done in the first place)

Thanks for taking the time to respond to all my questions. :thumbs-up:

No problem, Alex!

If you do decide to strip it down yourself - it is a fair bit of work, but nothing is particularly complicated, and actually it's likely to be easier to pull out vents etc now that they have already been out recently
Just give yourself a couple of full days (which should be more than enough!) to take it slowly without rushing, and post or PM any questions if and when you get stuck....

Think I'm going to try this one out, looks to offer what Naviplus does!

Gents, how do these systems work with back seat entertainment, for those of us who have that.?

The unit doesn’t really interact with the RSE. Certainly nothing from the unit can be output on the RSE displays. At most, I expect the RSE can select the aux input to be able to listen to whatever you’re playing via the unit.

If the occupants use the remote, there will be no difference to how it operates. If you normally do it from the main screen, you’ll just need to swap between the unit and the car menus to control the RSE.
