[QUOTE="ionbeam, post: 1245792, member: 277"] FWIW, I have my company's products run through Highly Accelerated Life Testing (HALT) where the primary tests include applying strong vibrations at different frequencies while concurrently heat cycling the item being tested as a means to get it to fail quickly. Kinda like what happens on the handlebars of our FJR. From what we learn during HALT testing we refine our product design so that weaknesses are mitigated and the product becomes very reliable. Motorcycle specific GPS should be more robust than most car type GPS due to vibration testing the design. Old school circuit boards with thru-hole components tend to be more robust than modern surface mount boards where the components have no leads making the components rigid and more prone to fracturing. Also, surface mount boards tend to have more latent defects which won't show up until much later in the product's life unless the manufacturer has good screening processes. Today's circuit boards made for the public no longer have lead in the parts or in the solder, however, for some military electronics and implanted medical devices lead is still used for improved reliability. Anything you can do to soften vibrations will vastly improve the chances of your GPS having a long life. [/QUOTE]
