Okay be gentle. (Sorry Ale. I went with the Floater)
I know this is not going to be to everyone's taste as it is a bit BIG on the dash. I live on iThingyOS and do use the car for business. It is a bit dominant but I can reach all the controls and A/C around it. Sound quality is really improved. They had to drop the dash to get all the cabling laid out correctly. Carplay plus DAB, Waze plus actual music coming out of the four speakers etc etc.
It turns out the Alpine built-in amp had given up the ghost not the cabling. Thanks for the comments re the location of the inbuilt AMP, it was in the front of the passenger footwell behind the plate. I really will have to stop listening to the drum'n'bass and dance music so loud.
I can rest my hand on the gear knob and it is in just the right position to use the touchscreen. The on-screen buttons are nice and big to use. As I often use the autobox in manual selection mode this is perfect. Carplay has a few limitations but for safe driving it is good. I like the Sony user interface (it helps if you have had a playstation in your past) however the up/down volume rocker is not as a good as a traditional round knob. Why do people have invent away from simple proven solutions.
I don't think the external AMP is quite man enough to manage the upgraded rear 6x9s if you do raise the volume, you can feel them getting a little bit tubby so it may be upgraded for one with a bit more control.
I will peel off the silly label.
I will hoover it
I will clean the dash
I promise.....
