Xcarlink help - switching between sources

Am I being a div? Standard head unit (not Nav) and I can't seem to be able to switch between iphone, SDcard and USB stick.

Pressed every button but cannot find it, thanks.

I didn't think you could remotely switch between the inputs on the XCarlink. You switch to the XCarlink and then it'll play whatever noise is being fed to it. Mine is the iPod/Aux version and the priority goes iPod primary, if that's unplugged it gives me the signal from the Aux.

Maybe your version is different as it sounds like it's a newer version than mine.

That's what mine does but it says you can... "[SIZE=10pt]Easily switch between all sources using the factory radio/navigation system"[/SIZE]

It does say you can do it via steering controls/navigation system but I'm wondering if its for Navs only.

Edit...good point Steve I bought it used from a member here and he referenced the above model but it might be an older version like yours, is yours in black plastic rather than white?

Black plastic, yes.

Sounds the same then, that explains it. Thanks
