Hi, I bought a Pioneer F70Dab unit.
I bought the corresponding Connects2 steering wheel kit and it works fine with Android Auto
At the time I looked at Android alternatives but I wasn't impressed with the start up times, occasional lag on the user interface, and in some cases loosing some of steering wheel button features.
If I were buying now I would seriously consider the 8inch or 10inch units from Xtrons that support split screen apps. They start around £210 and go up to about £300.
In fact, I'm thinking of selling my Pioneer in a few weeks to go for the 10 inch version.
I saw a YouTube video where the reviewer said it looked ugly from the side as the 10" unit protrudes from the dash, but I'd rather have a big screen running fairly reliable and mature android apps as I'm planning on keeping my 6 GH SL for another three years until I can afford a used 2019 estate with a 2.5 Turbo petrol engine.
