Yes. I installed it with my brother, who installs car stereo installations professionally. It took us probably close to 10 hours to install. Keep in mind we were doing the bluetooth mic where the moonroof controls are and the rear camera. The installation took much longer than originally anticipated but we kinda figured it would. No wires are showing, no shortcuts were taken, the install looks great!
The first month or so the Avin was great. I dramatically noticed an upgrade in the sound quality still using my original Harmon Kardon speakers.
Bluetooth Issues: The bluetooth feature isn't nearly as seamless as I hoped. With all the other bluetooth devices I've paired and used with my Galaxy S4 phone I've had no problems. When I mean work correctly I mean not having songs skip, jitter, stutter and phone calls sound gargled and too distorted to have a conversation with the other person over the phone. Unfortunately this head unit's bluetooth is very flaky and often-times requires unpairing and repairing for it to work correctly. Sometimes that doesn't fix the issue so you'll have to unpair and go the extra step of forgetting the device and doing a 100% new device setup.
Even more nerve-wracking then the bluetooth complications in the last 2-4 weeks I've been having issues where I cannot have ANY control of what the Avin will do. This is no exaggeration. Here are some examples: 1) Often-times the screen is 100% unresponsive or I'll touch the SD card (primary feature I use to listen to all my music) and it will choose a completely different input like Radio. 2) While listening to a track from a CD in the CD player the song will change all by itself to whatever song it felt like. 3) While listening to the radio I've literally seen the station be changed all by itself. 4) Early last week I wasn't even able to turn it off. 5) When listening to the radio last week I had the volume at around 3 or 4 (very low) all of a sudden the AVIN splash screen was on the display (like I just turned it on) and the volume shot to at least 20 and I couldn't turn down the volume until it finished booting.
It wouldn't be fair to mention Avin's support after going into detail about the issues I've been experiencing. I've messaged Tommy from AVIN a few times and he is suggesting me upgrading the version of android. I've already done a hard reset on the unit, setting it back to factory defaults and it made 0 difference. I still have all the issues previously mentioned after doing a fresh install of Android. Later this week I'll try to find time to follow his instructions of upgrading the version of Android and praying that the issues are resolved. I'm willing to bet that it won't, but I have to follow Tommy's troubleshooting steps before anything else can be done.
In Summary: It may be too early to tell but since installing on Sept 7 I can honestly say that I've had so many issues that if it didn't take 10+ hours to install this unit I would have returned it much sooner. I'll follow the instructions to upgrade and test everything again and I'll upgrade this thread after getting those results. Stay tuned...
