Not sure if anyone's still reading this thread, but I just did most of the Beat Sonic install. I was originally using GX Bob's video as a guide, but I think he has a 14-later model GX as the back of my nav screen has a huge box on it, I had a couple extra bolts on my nav and my wiring was much different. Switched over to the Beat Sonic video, not quite as detailed but I think I figured most of it out. Ran into two problems:
1. My hazard lights are going off now. Tried tightening / disconnecting / reconnecting the battery. Perhaps it just ran low? Not sure how old it is. I ended up locking the car and disconnecting the battery for the night.
2. Although my car recognizes my phone, it cuts out the audio when I plug the phone into the Beat Sonic USB and does NOT bring up a USB tab on the audio page. Therefore, I don't have access to Carplay. When I initially plugged in the phone after install, it brought up a Carplay screen on my phone, but that is the extent of Carplay that I've seen.
Anyone have either issue? TIA.
(Also, if you are planning to install Crawl Control and Multi-Terrain Select, it's a great time to do either if you're taking off the dash).
