Does nissan 350z have aux input?

The Nissan 350Z unfortunately does not come with auxiliary input capabilities in any of its few brief model years. However, You'll be pleased to know that several manufacturers produce aftermarket head units and modules that can give Your 350z the function for which You're looking, and they come at a relatively reasonable price tag. While You're upgrading, You may want to consider a bluetooth ready head unit. There are a number of different options from the likes of Bose, Sony, Kenwood, Alpine, Pioneer, Boss, JVC, and others which include both auxiliary inputs as well as bluetooth, and the swap is relatively simple. You can expect to pay somewhere in the neighborhood of upwards of $150 for a replacement head unit, and installation shouldn't take You more than a day.
