Had a number of faults on the dashboard including LCD and temp and fuel gauges not working, sent off the unit and it was returned very quickly with everything fixed and now fitted all are working as they should. Excellent service and very quick turn around even during this pandemic we are experiencing. Very recommended. thank you.
