About 18 months old. If you track your car and want an external GPS that plugs into your iPhone to let you use track applications like Harry's Laptimer, this does the job nicely. Includes extension cord so you can mount the GPS separately from the iPhone. Works perfectly, triangulates off multiple satellites. Free software online. Original specs at:

$99 new + $29 for the extender cable, I am selling for $50 including shipping.
(I am switching to a bluetooth GPS unit, fyi)
