I would think if their site had been hacked, they would have said so, as it would have been a legitimate excuse to cancel the orders. Saying it was a pricing error admits that it was likely their mistake, and they should honor the price, IMO. The amount of money it cost a company like Garmin before the mistake was discovered is likely not worth the bad publicity and PR that this will generate. If, on the other hand, they don't know whether the site was hacked, and they are investigating the source of the error, they should at least say that to the customers who have been affected.
