I have a 2004 LS400 with Nav. I have no desire to get rid of her, but I would like to modernize the audio system: bluetooth sync music from iPhone with audio systems, contacts with iPhone, play Pandora, Sirius/XM, etc. Anyway of this possible? Bought wife a 2014 RX350 and am kind of jealous of system, but no enough to leave the body of the LS430 for the 460. Advice or suggestions?

 

Check out vaistech units. They plug into the factory head unit and even utilize steering wheel controls

 

I second what greg s said... I have heard some good things about these units.

 

Also consider the Audiovox Mediabridge. It works on 2003 - 2006 LS 430s. Has bluetooth, usb, aux, iPod all in one small package. Vaistech is more of an a la carte solution unfortunately. You can't get all USB, Aux, iPod, Bluetooth in one package. Plus their prices are about $100 higher than the competition.

There is also Grom, but their design seems slightly more convoluted than the audiovox.

It should be said that I have no experience with the audio these products produce. This is all based on the research I've been doing on them over the past couple of months. I purchased an audiovox for my '01, not realizing it doesn't match up with the factory stereo harness. But I have handled the device. It's small and has a usb port and aux port on it. Pretty clean little box. May be selling it soon if I can't find a work around for the harness issue.
