I've got a brand new W8500 installed in my 2008 Toyota 4Runner. Overall, it's great, with one major exception. The GPS can take 10-15 minutes or more to track my location. I first noticed this when using Wireless CarPlay. My location would be wildly incorrect. At first, I thought there was an issue with my phone, but I then realized I was experiencing the issue with the built-in navigation. That confirms that when connected wirelessly, the phone uses the 8500's GPS instead of the built-in GPS chip. Which would be fine, if the 8500's GPS actually tracked my location quickly enough.
