Just test driven a 2014 500 S, planning to put my deposit down tomorrow!!

So many questions I forgot to ask.
The website has this -
MP3 compatible radio/single CD player
Blue & Me with USB port

It has aux sockets and a usb.
Will my iPhone need to be used on the aux or can i connect it via usb and control it via the radio?

Also, is the bolt on tom tom worth it?
The car has the hole for it and I am considering getting one.

Rather excited and enjoying reading up lots of interesting stuff on here.

Jess.

I don't have Blue & me, but from what I've read here its not as good as some systems and has more issues when using a I phone vs Android, music streaming can be a real issue I've gathered
