thanks in advance for the help

my question is i have the telenav and the bluetooth which both hook up with the plug that is blue and black...do i run them in tandem? do i hook one to the hu and one to the other box? and if i am running them to the hu do i still need to run power to both boxes?

You hook them up in a chain. One IP-BUS cable from the head unit to the first module, and another IP-BUS cable from that module to the second one. And yes, you have to hook up power for them both.

ok thanks alot..
