I'm considering putting a Bluetooth connection in my 2005 Land Cruiser. I have had it since 2010. It has navigation. I tried it a few years ago and it did not work. Also is there a system that will work with the CD, FM AM etc. and not create a need to abandon any of those? I have done a little research and want the best sound possible and consistent volume settings. Also, does anyone have a satellite radio hooked into the OEM head? It looks like it toggles between AM and SAT any advice is greatly appreciated.
