Wal, I don't have the J&M setup, but had a similar issue with an Autocom system.  The Zumo wire into the base unit needed to be in a socket that was for mobile phone use to allow for talking back. If it was in the other input only sockets you could hear but not speak.

Thanks Saaz ill give that a try

Dont forget the cable from Zumo to system MUST have 2 connections to Zumo cable, one (2,5mm mono)  is the voice back to the Zumo thence phone, and the 2nd (3.5mm stereo) is audio out of the Zumo to the system.
As SAAZ says the system socket used must be the PHONE one not the "GPS" one
