I am looking to fit an RCD 510 into my 2008 Golf R32 and i have a couple of questions...

Given my car is a 2008 ( MY2008 ) car. I think i should have the updated 'L' or higher CAN module? So i shouldn't suffer the battery drain issues??
And i have a full height MFA..... So other than the aerial adapter (i understand this is part number 7L6 051 551) I think my car should accept the unit without any need for coding/programming? Is this correct?

So my main questions are - Given that i am fitting the unit for two reasons:

1: The Bluetooth integration
2: It looks much better than my factory RCD500

1. Will i have to route a microphone cable for talking hands free? I don't relish having to do this, especially up the A-pillar trim where there are SRS airbags.
2. I have a Samsung Galaxy S7 - Will i be able to Bluetooth music and/or will my factory (armrest mounted) Aux in still work?

This is the very unit i am looking to buy:
