Hi I have 2005 sport Tdv6, these are my problems hope you can help
I have screen displaying no navigation available
Voice control not working
Sat nav doesn’t even start up or let me eject disc
Had new updated Bt module from Wiggsy so we can assume that’s ok
If I put by pass loop on the most system at the module I get sound on radio re plug it into module no sound
Sat nav originally worked then started flickering then went completely
Phone paired to start with but caller couldn’t hear me and had to enter code each time now doesn’t even pair (I phone 7s)
Have tried fuses relays as others have suggested and tracing wires for breaks etc to no avail
Sure there’s more but, hope you have some new ideas out there
Have also tried replacing sat player with other one same problems

It sounds very much like the unit under the seat you say you changed.

I would do this: should eliminate nav problems
Works with D4 BT

What are you bypassing ? The display ?

No the Bluetooth module only way to get sound on radio

replace fuse 52 behind glovebox

or fuse 58 if the LCD isn't working

Wish it was that simple been through all the relevant fuses and changed them no joy
