Android Auto Retrofit Query

[Cynide]

Hi All,

I'm currently using my Samsung phone as my maps on my 2013 A4 2.0T and wanted to know if anyone has done a retrofit for android auto. I'm not too keen for putting a screen in front i.e 10.25 inch and the original screen seems closer to 7inches. The 2 that seem quite similar and 'should' allow android auto and using the cars original screen and steering controls could be:

2) https://bavarian-automotive.co.uk/products/audi-wireless-carplay-mmi-interface-unit-for-apple-carplay-and-android-auto-audi-2g-high

My friend was trying to push me towards the new Mekede Dudu 7 but they don't have an original size to fit this model car. Looking forward to any thoughts or advice on this.
