The GPS Satnav CD player/Radio finally after ten years failed to work anymore, and I went to a car parts place and purchased a replacement one. I was fortunate to call Monster Car Audio to get them to install this replacement one. The service at monster impressed me. Alex ( at the Erina branch ) is friendly, genuine and very professional. I am very pleased to recommend this company to anyone wishing to get a car stereo, reverse camera, car alarm or any other installation. Thanks for your good service.
