UDPATE
Sooooo... Stupid me. I accidentally put the Optic plug in the wrong Quad Connector - LOL! So that is sorted.
The system is installed, and working - ALTHOUGH - Not working as it should exactly.
When I go to CD, I get Mr12v Listed, and 3 tracks. I actually have to select Track 2 in order to get the thing to work. See attached - Strange.
LASTLY - Making a phone call is impossible. The Audio from the Mic is awful. I have done the Echo Correction etc, but no good. If I am sitting still it is fine, if I drive nobody can understand me. They say it sounds like someone rustling a packet of crisps! LOL!
As directed by Mr12v I plugged my new Mic into the unit - not the splitter.
Anyone experience this?
