Dear Scryer21

If you purchased 68A from a Dealer in your area, you would contact them to purchase the upgrade to 6.8B. This is not a ptf - it is a totally new version of the product.

If you need information on a Dealer in your area, or have further questions that are not of a technical nature, you can contact our Customer Service department by email: customerservice@softrak.com and they can assist you.

Regards
