Okay I think I have progress.
I have a Jan built 2013 i30 Elite 4 door hatch with Sat Nav. If my research is correct, this means I have the stock LAN1050EHGD head unit which has a slightly different form factor. I'm not sure however if I have a GD or GD2.
I found
THIS product which is stocked by Autobahn in Australia.
That page shows 3 options, GD radio, GD2 radio and GD2 radio with sat nav. I called Hyundai and the lady said I have a GD (based off my VIN).
THIS PICTURE on the product is exactly the head unit I have but it's listed as a GD2.
Before I pull the trigger on the "GD2 with sat nav" could someone please be kind enough to confirm that's the correct kit for my car?
