SMS to Speech and voice dial through Prius base sound system?

[scolab]

I just switched to an LG G3 on Verizon from a Lumia 928, which I loved, but hated the lack of carrier support. My Lumia would allow Cortana to read my incoming text message through the sound system and would also allow me to reply through the sound system. Absolutely loved this feature. I could also speed dial a number that would bring up Cortana to allow me to voice dial or voice text anyone in my contacts.

Contacts don't sync with my Prius either like they did with the Lumia.

While this isn't quite a deal killer, I'm really hoping there's a way to do this with the G3 because I really love the hardware.

Thanks!
