Well I bit the bullet and purchased the Alpine ILX-007 head unit, this unit is not currently available in NZ due to Carplay not being officially supported by Apple for NZ.
My first impressions are that the interface is a little slow to react at times but is otherwise pretty intuitive. Siri works ever better now with the head units microphone that on the phone directly, you can use the "hey siri" function for navigation and things like turning music on. Unfortunately there are very few apps approved for Carplay so my Tomtom app doesn't work, however the apple maps does, and actually works quite well via voice commands.
For an Iphone user I can see that this really is the future as far as in-car technology is, I landed my unit for $1250 with a 7 inch screen and pretty darn good sound quality as expected from Alpine, that also included GST in Australia and on arrival in NZ so if you dealt with a company that knew how to sell less GST that would come down by about $100, or even better purchased in Australia and claimed the TRS rebate then lied to NZ Customs on returning to NZ.
Does anyone else out in Geekland have one of the Carplay units and can recommend apps optimised for it?
I have a tuning app call Dash Command which has applied for certification and hopefully will be able to update with this soon so I can see the cars performance on the screen, not for any other purpose than is looks cool!
