Hi all, Newbie to this forums. Anyway just picked up a 2011 golf tdi MY12 (missus car) and was looking at options for slowly upgrading the factory headunit and then stereo speakers. Currently it has the RCD310 with BT and MDI and MFD capability. I would like a unit to which we can retrofit a rvc to at a later date and sat nav would be a plus.

Just a couple questions on the head unit side of things -

1. If i was to go to RCD/RNS510 who are the mot reputable sellers on ebay to pick up these units from?
2. Eonon / Audiosource / Chinese after markets etc. Who are the best and most compatible (BT/MDI/MFD)?
3. I have seen a kenwood especially designed for the VW mkv/vi on other pages (DNX525DAB UK i think it is) does anyone know if this or similar is available in Australia or of any other good high end third party (Kenwood/Pioneer/Alpine etc) units that integrates seemlesly with the steering wheel controls and/or MFD.

Just trying to sus out costs and plan a budget for this.

Any tips welcome, Cheers in advance.
