Issues with Nav,blue Tooth, steering wheel lights also what about nav hack

Questions for those who have 2007-2009 models with Package 5/6/7 as long as you have the JBL system and sub/Amp Combo. With nav

Anyone solve the issue of the blu tooth and the Nav not going through speakers or picking up your voice after install of aftermarket radio ? or buttons working on steering wheel (just the blue tooth functions and the nav voice function) (*I have the PAC swi-rc installed for the other buttons to work)

For those who don't know most things go though the factory radio... for the steering wheel functions

both work them selves just there is no voice like it did with the factory radio

also after disconnect of factory radio the steering wheel controls don't light up when you put on the lights.. seems to go though that also?
