Satnav Systems Ltd in Surbiton
My VW Golf RNS-510 navigation system stopped working. I took it to my local main dealer who said it was not repairable and I need to replace it at the cost of almost £2000!
I found Satnav Systems and they diagnosed the fault and gave me an estimate straight away. I gladly accepted and they fixed and even updated my unit while I waited for a fraction of what VW wanted to charge. They offered me refreshment and Wi-Fi while I waited and were very professional and courteous.
Needles to say I am very happy and do not hesitate in recommending them.
