That way you get volume control over the prompts and the pillion get to tell you you have gone wrong. I just had to ensure all the BT was disabled, GPS and bike. I had a dongle but just used it for auto answer in the phone, which also goes through to both helmets. Price sounds OK with all the bits.
I have since upgraded to a Nav V, so I'm getting sound through the bike speakers. The BT dongle powered via the switched relay gives distracting hum through mega-sensitive in-ear monitors (completely unnoticeable through the headset speakers) so it is disconnect from the Autocom at the mo'.
