I still have about 100 codes for this free PC program. The code is good until December, so if you want one email me at info@fishxfl.com and I will send you a code. After you receive the code:
Go to www.navionics.com
Click on downloads and updates
Upload the loader
Click on Navionics PC App
Click on buy a PC app.
You will then go through the selection process of what area they want. At the end they will see credit card info and voucher code. The voucher code is where they input the promo code. Then let it download. FYI this can take A WHILE!
