Not so many changes as in the previous version, but Lazy Car 3.0 is here nontheless.
The main feature that was added (and requested a long time ago) was making TTS heard through the BT headset. This is now possible, if enabling the "Through BT Headset" option under "Incoming Messages".
Other than that, there were various other changes & fixes, such as the Notifications getting an update (and it's now much more customizable), and rearrangement of the settings screen.
Have fun using Lazy Car, and look out for a few more updates already on the way =)
