Audio gateway never sleeps and drains battery. Gateway now completely failed and dealership wants $2,295.00 (not inducing labor) to fix it.
No audio/phone/navy off and on...
Radio was going in and out, just shutting off coming back own for about 2 weeks and finally just went completely out...strange thing is,I had no issues until after I had my B service done at the dealer...Uhmmm
No audio. Only an odd "tick" "Tick" "Tick tick" sound alternating from each speaker. Command unit displays fine, satnav, radio, etc, but no sound at all other than that described above.
No sound or blue tooth phone voice. Appears it is a Gateway Module problem. $800 to install new gateway.
No sound, radio, CD, phone. Everything else works fine, Navigation, system settings... etc.,
