A quick question for those who have either retro-fitted the factory Bluetooth (as I have) or used the vauxhall mic and roof wiring as part of an after market kit.
Has anybody had issues with low microphone volume? It does work if you shout or are very close to the mic but is currently not really usable on the move.
I'm guessing it probably requires better quality cabling and solder the wiring in one big run rather than going through a series of connectors.
However, before I pull the wiring loom apart again, any thoughts on best way to fix this appreciated.
