MkI VRS replaced stereo headunit - a few questions

Hello,

Ive just replaced the standard Symphony Stereo Headunit on my MkI VRS, with the unit from my last car. I've used an ISO wiring harness adaptor to facilitate this change, and just want to check a couple of points out.

Firstly, the new headunit will not turn on, unless the ignition is at the "I" position - is this correct? I believe the Skoda unit would allow you to turn it on regardless of wether the ignition was on or not?

Secondly, i havent fitted the amplified aerial adaptor as yet, (namely due to a lack of space behind the headunit leading to frustration when i was installing). If i were to install the Aerial adaptor at a later date, whereabouts would i need to connect the blue wire that runs out of it to? My guess is that it will need to be connected up directly to the headunit, on the connector marked "AUTO ANTENNA OUTPUT"? Is this right?

Cheers!
