I tested a Polo GTI this morning and i've been reading through this forum and the AV forum. I want to place an order for one tomorrow but I have some questions about the options vs. the aftermarket route.

1) Can I connect the iPod MDI to an aftermarket AV & navigation solution from Pioneer or Sony?

2) Can I connect an aftermarket AV solution to the telephone buttons on the steering wheel? (some posters suggest this can be done with a visit to the dealer to upgrade the phone's hardware).

3) Is there a good AV dealer in Sydney who can get this done without making it look bad (ie - no dangling microphones etc).

Other than that, I'm thinking GTI 5dr / Black / Comfort & Audio... any thoughts on the bi-xenons? Seems a bit steep at $1600?
