Hi all. Thought I would ask if anyone has used any of the companies that sell copy SD cards for built in Sat Navs .?

Im looking to upgrade a VW RNS 315 system from 2012 but the SD card from VW is 145 from a main dealer !!

On the internet Ive seen a couple of companies doing the latest version for about 35.
One such company is latestsatnav.co.uk which does get decent reviews on trustpilot etc.

Im a bit wary of using a copy SD card which may damage my system, but I do tend to be old fashoined or over cautious when it comes to such matters.

Regards Victor
