Spent £400 on a Snooper Sat Nav, now on my 3rd SD card. I'm a professional driver who relies on a decent system with good customer service, sadly I haven't received either. Why don't they send out a loan unit ? On my last encounter I spoke to the technical dept, who gave me contradictory advice, compared to the previous encounter. Had to pay £20 upfront for a new SD card plus £10 for next day delivery, which took 3 days to arrive. Have had the £20 refunded but still waiting for the £10, have rang several times and asked for messages to be passed to Alex Mangli to return my calls, but as yet, nothing. Have just rang again at 13.50 on the 9th August to hear a message that customer services are closed ! Sorry guys, you have pushed me to this damming review.
