I read several reviews on cases before purchasing for my 5 inch TomTom GPS.  I like this case because the GPS fits into it perfectly - but you definitely can't fit the cord as well.  That's my only complaint.  Love the feel of the case, and it sort of looks like an eye glass case, so it's not a big deal if you leave it on the floor of the car when you leave.
