Awesome upgrade to old stock Bose system
2000 GMC Yukon Denali
Ease of Use
I installed this head unit to replace the OEM Bose system in a 2000 Yukon while upgrading the speakers to Alpine Type R but leaving the OEM Bose Amp and Subwoofer as I wasn't ready to replace them at this time. This unit has greatly exceeded my expectations but particularly in its Pandora functionality and with other bluetooth features. I have a budget friendly LG Stylo2 running 6.0.1 (Marshmallow) which was released late 2015. My phone has connected with bluetooth each time I've gotten in the vehicle in the two months since the install. I really like how after only about 15 seconds the bluetooth connection is made and if the source is set to Pandora my current channel immediately starts playing. I used the Metra wiring integration device and also removed the separate Bose single disk CD player and installed a replacement pocket which holds my USB cable and the microphone which I attached with a small piece of velcro. The sound quality for phone calls and for music is excellent. Since I do not like the stock Bose Subwoofer in the Yukon I turned it off on the head unit and if I had a criticism of the unit it is that this did not completely silence the subwoofer. However, I installed the Alpline TuneIt app on my phone and used it to turn off the lowest bandwidth range which effectively silenced the subwoofer completely. Plus the overall sound is much better when TuneIt is used.
Pros: Great variety of sources including HD radio, USB, AUX, music CD, and Pandora. The bluetooth and Pandora functions using my phone are excellent. Very good sound quality and the ability to apply 9 band equalization with the TuneIt app. Very good music sound quality and also for phone calls.
Cons: Subwoofer off setting did not completely silence that speaker. Saving and retrieving settings on the TuneIt app is clunky but effecdive.
