as to your radio problem , I once had a similar 'hick up' w my system. , I took it to the dealer the following day , they confirmed I was in need of a software update , which was done then and there , end of problem.
Tires , vibrations small noises , etc on a new 100k vehicle have a funny way of being ever so more noticeable than on my 20k vehicles ( funny thing that) .
My personal decision for these smallerproblems has been to let it go for a while( 5 thousand miles or so) and see if it sorts itself out. true problems stand tall , nuances show themselves as such and hick ups will get aired out..

Most of all enjoy your new magic carpet
