I have a VAIS in my 07' LX. Install was about 30 min, the unit tucks in on the side of the air vent in the center stack, and you can run a charging cable from it to charge your phone if you want.
It picks up bluetooth from my Samsung phone every time, and the it displays the song on the Nav screen. All steering controls also work to control the phone, volume, track etc.
Essentially the VAIS has been flawless for me.
What model did you install? I'm looking at the SL3B-T and the MML-T1 but don't know which is better for longevity and tech advancement. The factory BT works fine (enough) and all I really want is the best product to play music/stream/charge via USB.
Anyone else desire the same thing and/or experience problems with outdated software integration with VAIS? If I go SL3B-T, will I need to update anything as time goes on?
