When Pioneer first launched their line of Android Auto compatible head units, the cheapest one which is the AVH 4100NEX, was priced at about $800. Now just a few months later, it's dropped down to just $544.89 over on Amazon. Which is a pretty good deal, if I say so myself. I have this unit for all of about 24 hours now, and so far I'm pretty impressed. Not only does it do Android Auto, but you also get HD radio as well as Bluetooth and a slew of other features. If you've been wanting a new stereo in your car, then this is a good one to pick up.
You can get the Pioneer AVH 4100NEX right now from Amazon for just $544.89.
