Why don't Fiat Ducato's (2010) have an auxiliary position on ignition switch

Why don't Fiat Ducato's (2010) have an auxiliary position on ignition switch like most cars do because even though it has a constant live connection to radio multi plug my head unit will only come on with ignition on, I was feeding both connection via a constant live but (I think ) the bluetooth was hyper sensitive and when ever I walked past it triggered the head unit to start up and have had those at home phoning me to say its blaring out music.
Not a major problem just wondered why no auxiliary?
I will have to fit a diode in ignition live feed so I can put a switched constant live connection back in ( tried it lit up dashboard), just means we cannot have radio on with engine off, I was same with Ipad thingy that had sat nav/reversing cam. when we got it running off a cigarette lighter plug.

Odd, isn't it. The 2021 model doesn't have one either...

I just bought one of these switches to mount on the dash

Amazon product ASIN B09KM3GVN1
I already have a feed from the leisure battery behind the stereo, so I am going to rig the switch as

position 1 = vehicle battery, on with ignition
position 2 = leisure battery

Still actually got to get around to wiring it though

cheers,

Heh, exactly the same here - have the same switch, but it’s still ‘on the list’

It did recently occur to me that as we have a battery master fitted to trickle charge the engine battery, maybe we need not bother and can just override the switched live and run from the engine battery as you say.
