We wanted to replace the radio in our TT which had an in-dash type. Since we have had satisfaction with HD at home we went with an in-dash HD and have been quite happy. There are several choices and I don't think it matters very much which one you choose. The value with the HD is the additional choices with the various stations, very nearly like satellite without the charge. Of course if you are not in range of AM or FM you will not have choices other than the option of CD, memory stick or getting out a book, you know that thing like an unplugged gismo with printing.
