The physical install was about the same as any the of the other stereo add-ons (Grom/VAIS/USA-Spec) for our vehicles, that emulate a CD/MD/DVD changer. Mine is installed on an 06 LX.
From the threads that I've been following, it seems iPhone users are having a better user experience with the VLine than Android phone users are. As an iPhone user I've gradually moved from the native DashLinQ interface over to the CarPlay interface and have been pleasantly surprised. I saw something about "Android Auto" now being able to be side-loaded, but haven't tried it.
I pre-ordered the VLine in 11/16 at a discount ($299), which felt like an incremental increase over the VAIS SL3B ($229) that it was replacing. When I first installed the unit (late 12/16) it showed lots of promise, but didn't really feel worth the money that I had spent on it. If they've truly got the "boot loop issue" (my biggest bitch) resolved with this latest firmware, it has just become worth every penny that I paid for it. If they continue knocking out the other minor annoyances, I can see how it could be worth the full retail price of $499 in a short period of time.
