Brought myself an RNS-E map update disc on eBay which arrived today. To be honest I'm a bit unsure wether to put it in my unit or not. It's just as the seller described and they have 100% feedback but I'm worried that it could do something that's irreversible. Has anyone else on here had any experience with these or horror stories before I proceed?
