I installed the Honda Hack from autohack.org
So far, so good.
I have a hotspot that stays in my car, so as long as it is charged, I have connectivity. The hotspot is connected to a 10000 mAmps battery, so it lasts about 3 days.
I installed the Chargepoint app, and I am able to access it finally.
I noticed some slowdown and the unit takes a little longer to boot, but it is negligible.
Haven't used it for google maps or Waze yet. You can install it on the headunit directly.
Essentially, it becomes an android tablet with full installation privileges. You install the apps straight from the app store. I recommend creating a gmail account just for this, don't share your main account
