So I've been searching on the web and on here for a while and have yet to find a definitive answer to the age old question of bluetooth integration for the iPhone4S. I have an 07 GS350 with Nav and am about to buy either a PA20-toy, BT35-toy, viastech, or the DICE Mediabridge. Looking for the best consensus on functionality and maintaining the stock steering wheel buttons and NAV touchscreen. I don't care if it is truly wireless or not since i will want to have it charging most of the time anyway. My main concern is that if I install the BT35-toy or similar BT solution, there could be issues using the stock BT phone functionality by having to connect to both the stock BT and the aftermarket BT (I do know that the aftermarket solution supports BT phone function, but would like to continue using the off hook and hang up buttons on the wheel and ultimately the stock phone functions). It would be great to be able to use Siri from the stock voice command button on the wheel, but I'm not sure that is possible yet. Any ideas or feedback would be great, thanks for listening!

 

Do you have the ML audio option?

 

Dont believe so. No sticker or dash emblem...

 

Just bought the PA20-TOY. Seems like it does its job well. Plus i tested my iPhone 4S by plugging it into another ipod interface radio in another car in my garage while it was connected to my GS350 via the stock bluetooth phone connection. Was playing music to the other car, and used siri to make and end a phone call. Music paused and allowed the phone call, once i hung up (via the on hook button on the wheel) the music resumed normally. So i have to imagine the functionality works like it should with siri and the stock bluetooth phone setup. Once i get it installed and working, i can update on this product for the 07 GS350 with nav / no ML audio.

 

I use the Vaistech SL2Vi and can run video as well. Don't even have to be jailbroken. (I have a 4S)

If you use Motion X GPS (a $1 app), it will run dual-screen and kicks the stock navigation's a$$.

Video / upgraded GPS... all signs point to Vaistech. Love it.

 

Only paid about $100 for the PS20-TOY, and from what i have read, works pretty well. For my wife's car, so not too concerned about its "amazing" features like the video and nav since she probably wont be able to figure it out anyway. If it sucks, I'll end up getting the Vaistech since their corp office is right down the street from me anyway.

 

So with your Vaistech, you can use the iPhone with Motion X GPS on your screen while driving?

 

Yup. It works brilliantly! Even has the speed limits and all that stuff.
You just have to ground the parking brake wire and snip the speed sensor wire. There are a few DIYs on here that are good at showing you what wires.

 

do you guys know if this kit will work with an 06 with NAV.....? everything im reading is from 07 and on...

 

From what I understand, it will not work with any ML cars.

Do you have ML audio? (there are very few with nav and without ML, but had to ask... you very well could have one)
