I upgraded to this unit from the AX150 about 6 months ago in my fully restored 1998 Jeep Grand Cherokee 4L. Since installing the unit, my car battery goes dead after 4-5 days (I'm on my second new battery). I've had my electrical system traced by a repair shop and they keep coming back to the XAV-AX4000 drawing power when the car is turned off. I've taken it back the installation shop several times. They keep pointing fingers at each other. I love the unit but am wondering if it is defective? Is there a known issue or update that stops it from drawing power when off? They replaced my car power outlet (always on) with a phone charger that is attached to the the XAV-AX4000, could that be the issue? Is it always on drawing 20W? Help!

My new Sony XAV-AX4000/Q was professionally installed yesterday. The installer was very impressed with the quality of the unit and included accessories. The steering wheel controls fuction with the adapter box. I like that it will show which door is open or ajar plus the tire pressure in each tire, excluding the spare. The vehicle is equipped with a SiriusXM antenna for the OEM stereo system but the installer could not get the antenna to work with the new Sony unit. I'm not a subscriber so it's ...

I bought this item to upgrade the stock radio for my vehicle with new convenient technology. This unit did not disappoint. The feature that I was most interested in was the apple car play feature. This feature worked flawlessly. I would recommend purchasing a plug and play kit if you are going to install yourself, however, if you are well versed in car stereo installations, it is not very difficult. The unit fit perfectly in my vehicle and does not look like an aftermarket install. I am very ha...

The sound system is so clear and crisp and smooth. The music is powerful and the camera interface is perfect. I can move around the various settings easily. It is a very intuitive interface and easy to understand and navigate.

I purchased a new AX4000 for my 2016 Jeep Wrangler and I love it. Connected with Apple Car Play gives me the ability to use all my apps.

I just had this unit installed and it is wonderful. I'm now in the updated world of a very user friendly stereo +

overall great receiver pretty easy to install i like how the screen drops down and looks great in my car

Great unit that fits in my 2005 Sequoia, android auto compatible.

I thought it sounded amazing nice and clear no static.

I wanted Android Play in my truck and that works great. I am still getting use to how to operate the unit between Tacoma OEM features and Android Auto. Not all the features work that were part of the Tacoma system, but the Google driving feature was the most important and that works great.I wanted Android Play in my truck and that works great.

This stereo is pretty subdued looking compared to many. It has a lot of useful options and the CarPlay is great. Surprisingly, to me at least, it even makes my stock speakers sound better on it’s own. This stereo is pretty subdued looking compared to many.

Pretty much everything you'd want as far as features. But, not all features work as well as I'd like, I.e. the tuner is very weak. Also I would very much like to be able to arrange the icons on the home screen. Why would they not put the phone icon there? While driving I have to take my eyes off the road to search for the phone app. Very unsafe! Updates are very hard to accomplish.

Great unit, super simple. I wasted money on an Android unit that had a lot of functions but was very cumbersome to use. Love this Sony unit way better and it has better quality radio for some reason.

Nice radio nice features hard to see in the sun sometimesNice radio nice features hard to see in the sun sometimes
