No sound on rns-E and No Tv

No the Bose pin is just to flatten the EQ on the HU, it doesn'r effec whether it works or not.
Chances are if the whole thing fires up and seems to be working but you get no sound then the "remote on" is not getting to the Bose amp (as all the speakers are active on the Bose system).

This one circled in red:

There's no difference, all Audi HU's have the same wiring.

You'll have to wire one in either from fusebox on/off with engine, or if you want a proper feed so it doesn't go off until you pull the keys out then you need to do the following:
Remove the trim under the steering wheel and you will see the main loom from the ignition switch running under the left side of the steering column. You'll see some black trunking protecting the loom. Release this trunking so you can get to the wires. You'll see a very thin red wire in amongst all the other thicker wires. This is the one you want.
With the ignition off and the keys out, chop this wire and reconnect it with a small terminal block along with another wire that you can then run to a relay. Unfortunately the wire is so thin that you can't get a reliable feed using a piggyback connector.
This is a very low current feed so you can't power anything directly from it. Just wire in a 12v relay using piggyback connections from the perm live & earth at the HU and use this new wire to switch the relay on/off, then use the other side of the relay to power the new HU. Sounds more complicated than it actually is, took me 30-45 minutes to do mine, but well worthwhile otherwise you need to have the keys turned to ignition on to get the HU to work when parked up.
