All D3's were 2G high or 3G.

2G will power a hard drive, but wont power the bluetooth dongle in my experience....

I've bought this - quoted by Snapdragon a few posts back.
I have the glovebox out and was wondering - for powering the device with constant power, I've sourced an empty 12v on the fuseboard (at position 40 - Brake Servo??)- although there's only one side of the fuse connector there, so is it possible to buy a crimp connector that would go in the other side that I would then join together with the existing live side by putting in a fuse?
I was gonna bolt the -ve cable to the chassis - this is all to avoid splicing into the existing power going in the back of the CD changer as all that came with the installation kit were scotchblock connectors which seem to be too big for these small cables.

ScothLock connectors are TERRIBLE things. For the sake of a few bob, I'd recommend you get some heat shrink connectors and a decent set of crimps. You'll NOT regret it.

Kind regards,

DailyMike.

Finished the install today with a fuse tap into the horn. I now have A2DP bluetooth streaming, aux, and microSD card. Just the glove box to put back in now which I'm not looking forward to...

Nice, please report back on your findings - I am tempted to have one for Christmas.

I only just noticed what rSAP was doing to my SIM card - my first thought was my phone had a fault until I realised I was losing the SIM when only in the car. So I've set the car pairing to phone call only with no rSAP and then also paired with the MrVolt device for media. All was good with streaming through the media device until I took a phonecall. The music muted and the MMI took over to handle the call. When the call finished the music came back up on the MMI screen but there was no sound. It seems the MMI is not relinquishing the audio back to the media device after the call finishes.I'll have to investigate further. Another possibility I can explore is to let the media device handle the calls as well - I'd need to wire in the included mic.

Did you disable the Handfree feature of the media streaming device?
Does the music still show as playing or paused on the phone screen?

I have the handsfree part of the device disabled. Media device has been erratic, with my original issue no longer happening and streaming audio is returning after finishing phonecalls. The device does not always autopair when I sit into the car though. I ran a scan and got...

I'm presuming the gateway is wondering what's this new device on the network. Does anyone know what I need to code to get the new device accepted onto the network, or is it that I have the new device in the wrong location on the MOST bus? If I check the Gateway installation list in VCDS, Media Player1 is unchecked in the list...

I had the same thing when I fitted an mp3 changer beside my original CD changer in the glovebox. The trick was to tell the second CD changer that it should assume a different network address (I think CANbus not MOSTbus address).
It was to jump two pins on it's connector - one spare pin was shorted to ground. I will try and find it. I am not saying this will fix your issue but is a good place to focus.

I've managed to get the device accepted by the Gateway and onto the network with no faults showing. The only thing I have now in VCDS is that Media Player 1 'Cannot be reached' - but it doesn't throw an error.
The device is working OK although it could be more seamless e.g. I often have to manually start up whatever streaming app I had been previously listening to when returning to the car whereas, with other bluetooth head units, the device will automatically resume the bluetooth stream without any user input. It also doesn't always autoconnect when I get into the car so I have to take out my phone and manually connect. It does switch between stream and USB well, but SDcard seems to takeover completely when inserted, where nothing else can be selected,and often the SDcard itself doesn't play. I haven't tested the aux input and probably will have no need for it anyway as long as the bluetooth is working. Over all I'm happy to have expanded the capabilities of what was originally there.
