Question: Will this unit fit in a 2013 Avalanche
Document: WARNING:  This is definitely a &#34;do it yourself&#34; project. It comes with no instructions for installation or use. I installed it in 2013 Yukon and it was a perfect fit, looks fantastic and works like a charm. However, I spent several days prior to purchasing it, just researching the unit. It is manufactured by FlyAudio in China (minor support) but is the same as Advent and I found several of their manuals online.
The radio is a tight fit so you must take time to route your wires correctly. The final appearance is a spot on for a factory unit. Simplesoft apparently markets the radio. But the radio is mfg by Fly Audio the manual indicates this. Overall I am extremely satisfied with the radio!
I kept the OEM bluetooth, and can't comment on the nav unit bluetooth. It is so good in the 2013 that I didn't want to fool with it. Ditto with the backup camera- mine is still on the rearview mirror and I get a warning screen from the radio when I back up. XM and Onstar work just fine.Setting favorites, both on the radio and the Nav unit, is a snap. The unit boots up slowly, as others have commented.
I am sure you all will be pleased with this unit.June 17th, 2013Since my last entry for this product, I have been sent a couple of emails asking if it will fit other GM vehicles. From what I can gather, yes it will fit. I have a 2012 GMC Acadia also, and same dash as the Traverse and Enclave it seems. This unit is a double din, and its mounting hardware and slots seem universal for the screw pattern for the other GM vehicles.
looked at a few $1000+ units and glad I found this one. awesome sound, awesome functions and functions work and integrate nicely. gps and nav works great!! high resolution screen. bluetooth handsfree works nicely. much better than the stock touchscreen GM comes out with. was easy to instal. nothing negative to say about this touchscreen. I highly recommend this unit. I have a 2013 CHEV SILVERADO 3500hd.
Bought this and had a friend of mine install it who has 12 years experience in installing car audio equipment. He stated that it was the easiest install that he had ever done. Things that are note worthy 1. After removing the factory stereo a portion of plastic will have to be cut out to fit the wires. This however is not a big deal as it will not effect structural integrity nor any cosmetics. 2. The power wire for the back up cam was not putting out the needed power for it.
I TRYED MY LUCK AND INSTALLED IT IN 2013 CHEVY SILVERADO BECAUSE IT SAID 07-12, BUT IT WORKS GREAT IN 2013 SILVERADO COULD HAVE MADE A BETTER CHOICE ALL FEATURES WORKS EVEN STEERING WHEEL CONTROLS, ONSTAR, XM RADIO I WOULD TELL ANYBODY ITS A GREAT BUY FOR THE MONEY, IT HAS MORE FEATURES THAN THE ORIGINAL FACTORY GPS!!!!!!!!!!!!!!!!!!!! I INSTALL IT IN 20 MIN THATS ONLY BECAUSE I INSTALL BACKUP CAM.
This unit works awesome, I love the back up feature, Satt. Radio, iPod and the navigation system is excellent.Thx
Unit takes a long time to boot program. Program has to load every time the car starts. Website is down so can't get instructions to make anything work properly. No one answers the phone. Appears they went out of business.
If you do encounter any issues or have questions, the customer service responds very quickly and gives you access to their forum. I have done the research, tried the product, and APPROVE 100%. To top it all off, the unit looks better than the OEM that GMC offers for $1,499.
Answer: Currently I have this unit in a 2013 GMC, it's not compatibly with IPod Port, or OnStar does not show on the screen. Currently the Chimes or Turn signals lack an option to turn up the sound. So you won't hear either when music is up. I have not been able to contact Customer service for to-do or help. Research this more before purchasing this options. Fit well, great sounds, but no customer support for problems
