We paid a little over $1,400 installed. The unit itself was somewhere around $700 and $700 for the installation. By the way, the installer had to drive about 200 miles to get to my garage, that's why I think the labor was a bit high. I did all of the electrical work and included the AV charger circuit when I pulled the permit to build the garage. Thus, there was a four wire, eight gauge wire sticking out of the wall and a 40 amp breaker 22 feet from the wall mount. The installer joked that why didn't he just leave his tools with me, go have lunch, and let me finish the installation.
However, it took some doing to get AV to quote this low. After a few attempts, some ridiculous, I was able to get a realistic quote. I started a telephone conversation with a Nissan rep and then requested that they transfer me to AV to straighten out the details. BUT, I said, please stay on the line so we (me, Nissan and AV) can get this straightened out. That brought results.
I have been totally pleased with the installation. The charger works flawlessly. Also, the installer told me that when AV sublets the installs to local electrical contractors, they appear on a website and any of several in the area can opt to get one. Because of the distance involved, it took a little time before a contractor was willing to put in the mileage to pre-inspect and install mine.
