My '07 IS220 sat nav module sometimes gives an error message stating 'insert correct disc' and can be noisier than normal. I can restart the car and it can work normally, I can't see a pattern to when or why this happens.
The car has been serviced today and Lexus have cleaned the drive but said they think the unit is on its way out and it would need to be replaced.
Does anyone know of someone who repairs the sat nav units? I would rather not try my luck with a second hand eBay unit, particulally as they are £1000 anyway.
Advice and thoughts welcome.
