[Android Head-Units] selnick:
My thoughts and personal experience: This A6 model is a multi-media head unit for automotive vehicles that is essentially an android tablet. It turns on in a second or two after starting my car’s ignition. Advertised functions work except hands free phone calling for which a work around is in progress. The screen is high resolution and brightness is adjustable. I mainly use FM radio, email viewing, listening to songs I recorded to a thumb drive using my computer, I pay attention to the rear backup camera image when in reverse gear and, while driving, am always recording video through my dash camera (a purchase option) for storage on a micro-SD card . The thumb drive and SD card are not supplied with the A6. FM radio brings in 23 stations in my area with good fidelity. Phone pairing was made easy by following the Owners Manual instructions carefully. I'm making and receiving phone calls with good sound quality on both ends. Call volume is easily adjustable but usually not necessary once set to my preferred level.

I haven’t had any luck, however, using Hound (an ATOTO recommended work around) to obtain hands free phone calling. Customer tech support is usually very responsive and spot on by knowledgeable personnel so I’m hopeful they’ll let me know how to get hands free calling worked out when fully developed. I'm surprised to hear that some users say hands free works for them. So I may not have the latest firmware properly installed. Either that or my A6 is buggy. Vacation videos and my prerecorded music play well from my thumb drive. When I use GPS I use it off line to minimize cell phone minutes and charges. If you have unlimited network use, you may prefer online GPS for better turn-by-turn driving guidance. Wi-Fi and Bluetooth connections between A6 and smart phone were easy to set up. Tip: If you don’t use your car every day, it’s a good idea to turn off the A6 before turning off the ignition. As with the predecessor M4 model, this model draws enough milliamps of current in support of its two-second ready-on feature, that after a few days of being parked, my battery is sometimes too weak to start the car. This is not an issue if you use your vehicle daily. The backup camera is a valuable safety feature, especially at night when it gives almost as bright and sharp an image of what’s behind you as during the day; things behind the vehicle that you could easily miss looking in the rear view mirror. The gesture control feature works but I find it annoying as it requires precise hand movements and a good amount of user practice. I must say, though, that it has quite a bit of WOW value with my buddies. I mainly use it to adjust music volume when I want to demo how it works. The optional wireless steering wheel controller is reliable. I use it for changing stations and music selections and to turn the volume up or down while driving. GPS software is built in for Waze, Google Maps and Tom-Tom.

Tip 2: A word of caution about installation. The section under "Power Harness Connection / Precautions For Making Connection" contains multiple errors. Accordingly, I used only the manual's installation drawings and the list of color coded, labeled harness wire assignments and had no difficulty with installation. I matched the car's radio wiring to the A6 harness, soldered and taped. Most users, however, would be well advised to purchase, if available for their model, the proper wiring harness plug-compatible adapter cable. It will save them time and the installation will be much easier.

As it develops improvements, the company has a good track record of issuing firmware updates at no charge.
