Where is the stock satellite radio so i can disconnect it?

2007 GS350

In 2007-2009 Toyota vehicles that are equipped with satellite radio: Unless the satellite radio tuner is branded as an OEM Toyota unit it will have to be disconnected in order for the module to work correctly

 

what do you mean. do you already have sat radio? the head unit is sat radio ready, but there is no tuner unless you install it
