2007 A6 avant multimedia upgrade

[simont46]

I would like to upgrage from the multimedia to something that includes bluetooth, sat nav, and ideally the option to play audio through bluetooth. Has anyone done this or got suggestions that are reasonably priced? happy to spend a couple hundred..

I'm a paramedic doing home visits in the pandemic, sometimes for poorly people, and sometimes to vaccinate the vulnerable. So could do with actual sat nav, instead of my phone wedged in the centre console!
