Pretty good app. I have a complaint about the heads up display... The speed limit of the road is not showing up. My speed limit is but the one that tells you the speed limit of the street you are driving in, is not working. Not sure if that's something done through the app or if I need to contact the delearship...

This app used to be great, but since the update, I can barely use it. While I don't love the change to entering your full password every time you sign in, I can deal. It is the fact that I can no longer start my car with it. Just tells me it fails and then locks me out of my car. The locking mechanism just stops reading for about 3 to 4 hours. Can't even use my door locks, nothing reads. I have to uninstall the app to get in. Paying to not be able to use.

I used to be able to use biometric login but now, all of a sudden I have to login manually and wait for an authentication code in an email. Also, every time I connect to the app it starts to "send a command" to my vehicle even when I don't initiate anything. And I still can't find where on the app I set it to allow biometric login (again). Please fix!
