That's still lame as s***.
Grom sucks, I have one.
Interested to hear why? I have them installed in 4 of my cars and they all work as intended without issue. 2001 LS430, 2005 LS430, 2007 LS460, 2007 GX470.
Music streaming, waze/google maps through the OEM navigation screen, voice navigation are the reasons I bought them.
