T5 transporter aftermarket radio options

[Husky310]

Here is a thumbs up to sunny. Thanks for your help yesterday. That talk we had, got the cogs moving in my mind.

For the others out there here is what I'm talking about.

Ordered a erisin ES3048v running lollipop 5.1.1 and fitted it to a 2015 multivan using just the factory wiring. Ordered from the wholesale site with the adaptor es350 for $380 including postage.

Problems I encounted was
Not powering on or off with the key.
Bluetooth was active even with car turned off and locked.
Reversing camera not showing up on the screen.
and a few other small menu problems.

After talking with sunny I found we both had connected the stereo differently. Me using factory, sunny aftermarket.
What I found was on the back off the unit there is some canbus switches. These turned out to switch wiring settings.
After a little trial and error got the reversing camera to work(with no wires except the audio plug in)
and the power settings now work correctly wich turns the unit off with the keys removed So Bluetooth is now only active when the car is.

So in summery user manuals are S**t and if using factory harness pay attention to the canbus switches. Members on this forum are an invaluable source if good information.
