Not many options off the shelf with these cars unless you are prepaired to to payout the cost for the bluepower unit which have very mixed reviews.
I routed my USB & AUX under the centre cover to a tablet on the dash (I keep my phone connected with the bluetooth)
Its not the cleanest fix but its mega simple and easy to use. I used magnet mounts on the dash which allow me to drop and remove the tablet real easyily.
The tablet I picked up for £20 second hand, just a small samsung one with the option to tether to my phone if needed but also hold offline music.
When tethering I get the combined use of both Google and Alexa making it hands free for navigation and for my music. I used to have a bluetooth / Aux adapter but found it real frustrating to have to constatly connect the tablet to the bluetooth, so just running it straight into an aux cable is simple.
Here is what it looks like in the link below if that helps, I have moved it up a bit more to see the screen for other controls as well. I just have one magnetic mount with a big plate on the tablet to hold it, along with 2 pads at the bottom to stop any vibration noises.
