Aftermarket interior ugrades (Technology focused)

[Vulisha]

Hello,  I am member from Croatia and I have bought new Toyota Corolla 1.33 (eg.  your Auris Icon package without halogens and Automatic A/C)  with basic equipment since I needed car ASAP and that one was only available.  Overall I am very very satisfied but I am missing two things.  

First one is touchscreen.  Is it possible to upgrade standard radio with Toyota Touch 2 with camera, and if it is, is price too big to upgrade? 

 

And seccond less relevant: I have small display with travel computer,  but that travel computer doesn't have current fuel consumption(all though on websites in Croatia it said that it has...)  which is so basic function,  my Astra from 2006 and Focus from 2011 had that function,  and it was my favorite travel computer screen.  I saw that bigger screen 4' has current fuel consumption,  so is it possible to upgrade speed gauge panel? 

 

I am willing to pay up to £1000-1500,  but since I don't want to lose warranty,  I want to do it in official service. 

 

BTW for £2000 I could have bought full package grade above,  but I had to wait two months :/ and I wasn't able to do that :/

Do you have the Corolla saloon, as that would be similar to the Auris, but not identical (longer wheelbase plus possibly other differences)?
