Citing "outstanding results from our partners' recent Dads and Grads promotions," Dash Navigation today announced a $100 price drop for its Dash Express portable navigation system. You can now get the Internet-connected GPS for $299 rather than $399, though you will still have to pay for the Dash Express service after the three-month complimentary period is up ($9.99 a month with a two-year plan to $12.99 per month for month-to-month). Now, while we certainly think that the grads and dads promotion helped spur the price drop, we can't help but wonder if it also has anything to do with slow sales? Anyone out there own this thing? And if so, what's your experience been like?
