New head unit install issue

[RafsZed]

Hey guys I have just been told that if I change my Bose head unit, I will loose volume on my built in sat nav, does anyone have any ideas how I can retain voice on the sat nav if I upgraded the head unit.

I have a Pioneer headunit (Came with the car) Unless they did something, the volume is fine (Scared the crap out of me!) But i've only listened to it once, and never opened the Sat Nav display again

You either need to add another speaker just for the nav or use an input source on the new headunit. I never got around to it but I was using the aux input and was going to try using the tel input so the music mutes.
