Hi, I apologize for the delay in reply. I've been out of the country with work for the last 6 months and unfortunately internet was verging on non-existant while I was there.
Personally, if you are not selling for profit/commercially (ie not selling them on ebay etc) and just making some up for a facebook community I have no issues with said recipients reimbursing you the costs for printing/posting. That's what this site is all about....Sharing.
I would however remove the garmin logo before doing so as they might not be so happy about it. removing the logo should be dead easy. I still have the original file and can easily upload a non-logo version for you if you wanted.
