Any reason not to get an Ipod nano 2nd gen 8GB for my 2013 XCT?This is what everyone has recommended I do believe.I have a lot of old Cds that I would put on iTunes and I guess they would load directly on to the Ipod with no hassle.would I have to change songs to MP3?I am very low tech so any advice would be great and there are lots of 2nd Gen Ipods available on Ebay.
