Hi Guys

I have fitted a xtrons double din stereo to my 2012 Abarth 500 and would like some help of routing the 2 usb cables from the back of the stereo to somewhere
accessible in the dash are without dismantling too much trim. Anyone done something similar that they can give me some advice.

Thanks
