FJRForums' Red-headed stepchild
I believe when the GPS companies figured out how valuable a headphone jack is for motorcyclist, they reserved that feature for their more expensive models.
The Mio 310X is old and dated but gets the job done (for me anyway) if you get lost. It works best for me as a supplement to traditional maps, so it's not for everyone but if you tend to only use a GPS when you need it, just thought I'd let you guys know about it, because I really like mine and it's hardly costs anything.
