Hi! Can anyone help me with a code for a Chrysler tape deck unit? The CD in my Jeep ceased working so I found a replacement unit (tape unit, this time) in a salvage yard, but has no code. seems it is an Alpine unit (any opinions on this are welcome, I am really curios if it is of any good). S/N TQDAA266758060, P/N P04704345-G, Date code 2667, Supplier 17719, Made in France !! Many thanks.
