Does the 2007 Toyota Avalon have aux input?

The 2007 Toyota Avalon unfortunately does not offer an auxiliary input on any of its trim levels or upgrade packages. It furthermore does not offer bluetooth connectivity, so if You want to stream music, You'll need to look into aftermarket options. Fortunately, numerous options exist which will fit Your vehicle. Because You don't have an auxiliary input jack, You'll need to replace the entire head unit to gain the functionality. This can be relatively simple, but also a bit more expensive than a simple bluetooth receiver. However, You should be able to find something in the $100 price range from a company like Sony, Boss, JVC, Bose, Kenwood, Pioneer, or Alpine. Of course, if You want to pay more, there are options ranging up to several hundred dollars for superior Audio.
