Question: do you need a parking brake overide or is it on product?
Document: Do some research on-line to determine exactly what you will need, otherwise you will find yourself waiting forever to correctly install the unit.The general consensus on negative features:1. The face is not detachable. (Would have been nice to have for when parking in the hood)2. The interface is difficult to navigate. (I disagree on that one)3. It takes forever to boot. (Mine takes on average 5 seconds which isnt too bad)4.
Also the target address is not displayed, if I could see the address I could easily decipher which side of the road it'll be on by whether it's an even or odd address, but since that's not displayed, you're usually left guessing if it's not obviously evident. Lastly, the safety controls are annoying beyond belief. You can't do or change anything with the navigator when the car is moving,  you have to have the parking brake set to input an address or change anything with the directions.
Also, when connecting the factory camera, I lost the helpful parking brackets.
Love the head unit. I have this installed in a 2005 Chevy SSR, fits and looks great. I wish I could operate some of the features without the parking break being engaged, but all and all it works very well. I wish the menu for the iPod was a little more easy to navigate, it's a little tedious to get to specific songs.
You can't beat the cost. This radio was $1,200 at bestbuy. I would have went to bestbuy to get a price adjustment but they removed the item very quickly. So far, so good! The only disappointment is it doesn't play the ipod videos (even with parking bypass). Also, it doesn't come with the ipod to usb/auxiliary cable (available on amazon for a few bucks). I bought a cheap one and it worked well.
I would take mine out if I didn't need to pay more to the car shop.
I installed this in my 2011 Tacoma with no issues. This receiver is more than you could ever need in a car. Pioneer has done it again.....
Fast shipping! Very secured! Very professional and everything I was expecting... HU in amazing! Very happy over all! Thanks! Easy to install didn't need for professional help...
"xcopy c:\mymusic\*. * e:\ /S". It will take a while, but the files are copied in folder/filename order - which is exactly what you need. Now the track ordering is perfect.
If I did, then I need to restate that. The z140 is a very quality head unit, and it will serve many of you effectively. My review was in written in relation to the z130bt, which it is not superior to. If I was simply reviewing the z140, without knowledge of the z130, then I would probably give the z140 3.5 or 4 stars.
Answer: You have to move the location of a pin in the harness. There are instructions all over the web and video on YouTube. Do a search for bypass instructions avic140bh. Otherwise there is nothing to buy. My one caution about this unit is that it currently does not integrate with the iPhone 5.
