Reviving an old topic for a specific purpose. I would have liked to had a little more information when I purchased this at the end of July. If it is the Linkswell T-Style radio, yes, many places sell these units. I bought mine locally in WA and had it installed, @CheezyDeezy like you I spent a few months looking at this, and watching the various videos on-line. My reasons for upgrading, I do not like the GM Nav, I have the 8" touchscreen, and I wanted the Apple Car Play, I don't have an Android phone.
I bought this in July and it is the beginning of November and I am planning on removing this, I simply do not like it. I used to be into android and modifying/customizing but I am just not into it anymore, nor do I have need for Video in Motion, the ability to watch YouTube, etc...etc...etc....most of the capabilities that make this thing cool are things that I do not or will never use. Items that irritate the crap outta me, If you have an iPhone and you plug it in, the CarLink picks it up just fine however, when you answer a phone call, CarPlay and bluetooth both pickup, seems it isn't smart enough to not answer from bluetooth when the phone is plugged in. Apparently this is only an issue for Apple and not Android phones. Because of this there are times when there is a few seconds delay in speech, either going or coming, like watching the news guys wait 7 seconds for the delay to hit them. Second, if you have sunglasses on, forget anything but looking at it head on, PITA when you are trying to drive and look at anything on the screen. Brightness at night, in the city, not really an issue but if you drive in rural areas where there are no other cars and no streetlights it is an absolute eye killer, you can't dim it or rather it doesn't dim but it is pretty easy to just shut the screen down, but again, PITA. Lastly, for me, it would be nice that when you start the truck, other than waiting for an eternity for the thing to start, it would be nice if how I arranged the screen previously, if it would still be there. I don't want to have to hop into my truck and spend 5 minutes waiting for it to start up, then arranging the screens so I can see Nav and Radio at the same time. Apparently there are ways you can do it, assuming you can set it up and then hit a shortcut or something but see statement 1, I don't have the desire anymore to customize. I like to be able to open car play and see Nav, Music and phone all on one screen by just pushing the existing layout......simple easy. It is a nice unit though. Bought the BOSE adapter for it which is specific to this radio, it retains all the factory stuff so no need to rewire or bypass the amp/sub, and it sounds pretty good without any other modifications. Maintains the steering wheel controls. Only thing you really loose other then XM if you have it is the integration into the 4" Display in the instrument cluster, so no more Navigation prompts or anything you use to get from the Radio. It has tons of stuff you can do with it, I added the DVR camera which works well and a third brake light camera, has some pretty cool stuff. Anyway, just wanted to put this here in case anyone was looking for one and wanted some more information. I will be selling all of the pieces of mine, Radio, Bose adapter, DVR camera, Third brake light camera and USB hub that I had them put in once I take it out in the next week or two.
