For what it's worth....with an Android phone I have downloaded Google "Offline Maps" which loads and saves a chosen section or area on the map and saves it to your phone. I would think that it would then work in the same way as factory navigation and then be using your phone's GPS. Here's a link to how it works. http://erinlyyc.com/2017/05/17/how-to-save-google-maps-directions-for-offline-use-when-travelling/

If I were in your shoes I would not go to a dealer. I would go to http://www.whiteautoandmedia.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=98&category_id=44&option=com_virtuemart&Itemid=54 and ask this question. Choose the "Ask a question about this product" link. Looks like you have the right HMI module. IMHO WAMS is the ultimate source for this. Hope this helps.

Thanks @GTPprix for the quick reply. That's good. According to UPS you should have both of my modules by Wednesday. Shipped on 12/27. Holidays slowed things down. As soon as I get this phase installed I plan on moving on to your cluster upgrade.

This may be a silly question at this point but I'll ask it anyway. I own a 2014 GMC All Terrain. From following this post I am sure that the 2016 HMI module I purchased has to be properly programmed to my truck's VIN. Does the 2016 radio module I purchased also have to programmed to my VIN? Does programming only have to be done to the HMI module? Like I stated, this may be a silly question but someone once told me the only silly question was the one that wasn't asked. Thanks y'all.

Closed. Bummer. I just received the necessary modules I purchased on 12/17. I then sent message through WAMS website and received receipt confirmation of that message. I'm am at the time thinking that I'm ready to proceed only to find out that WAMS is closed and not taking orders until 12/28. I guess at this point a little patience is needed.

Good information. Doesn't do much form my confidence though. Buying Ebay is like buying a pig in the poke. You're taking a chance.

Thanks Magpie! I can't thank you enough.

Magpie, Is the blue connector you mention like the one shown below? Thanks.

Thanks Magpie! I've followed your post on this subject but was still unsure as to what I needed for my application. Great work, I can go looking again with a little more wisdom.

This is a great forum with lots of good information. This is my first post. I know there's another post that goes into great detail on the topic of adding Android Auto to the 2014 model trucks. I have read all the way through it and am still somewhat in the dark as far as module part numbers for my application. Maybe there are others with the same question as me. This may also help them. My truck is a 2014 GMC Sierra with factory navigation and Bose system. I want to upgrade the HMI module and radio module to the 2016 versions and have them programmed for Android Auto. I understand I will also need to change the USB hub. In my case I'd like to also have factory Navigation available. My question to you guys is what part numbers for each of the modules needed. I am aware that Android Auto beats factory Nav hands down but I still want to keep it. I will appreciate any help. Thanks.
