Audi Concert Upgrade 2014 A5

[Welshauralius]

Hi,

I'm new here and hoping someone can help me out.

I've just bought a 2014 A5 that has the Audi concert system, with the display screen on top. It is bog standard and has parking sensors.

I am missing bluetooth audio and sat nav (lesser so the sat nav) so want to upgrade the stereo but don't want to lose the parking sensors.

What do I need to look for? I understand my model is 'double din' but I have absolutely no idea where to start for upgrades. I can do without the sat nav but I need bluetooth audio - using my FM transmitter with the sound system is not doing it justice!

Any help would be massively appreciated

Cheers
