Picked up one of these 9" Sony Media Receivers last night at the reasonable price of $748 from Ryda.com.au with shipping an additional $9.95
I've been keen on one of these the past few months and the price has been fluctuating between the different sites, best I've seen so far and hence why I pulled the trigger!
I plan on using mine for mainly Waze, Spotify and Google assistant via the Android Auto USB link.
Hopefully this post helps someone who is looking for a similar upgrade to their car audio.

Edit: As mentioned by CyberBlade, AutoBarn has the same unit currently on sale for $745;
