G20 after report of no sound. Jumped in car and there was sound but it was distorted. Having dummy module on hand, swapped it over and still no better.
Checked wiring and was within tolerance.
So it was mission to find sameday bass speakers and suitable module.
Trims cleaned before refit, music test complete and car is back on road.
Did navigation update to LIVE 2025-4 too
