Had been looking at a replacement 12 volt car power adapter for a Garmin nuvi 205w GPS that had been given to me by friend who was replacing it with a newer model GPS. The electric conductors in the power cable had become frayed and apparently actually broken at the USB plug end so no power was getting into the GPS and the nuvi was unusable for her. The strain relief molded into the USB plug had actually broken from the constant the bending the cable undergoes when the GPS is being transferred from car to car in a multi car family or into a purse or briefcase and its breakage had facilitated the conductor breakage. The model number of the original 12volt adapter, the one that came with the nuvi 205w, was model 00239-24. Best Buy has for a long time stocked Garmin branded accessories so that was the first place I headed. But, when I priced the replacement adapter it was around twenty five dollars or more – not worth it for me for this older nuvi 205w GPS with its outdated maps. Recently one of the sale e-mails I get from Best Buy featured a Garmin 12 volt vehicle power cable adapter at a sale price that was ten dollars less. I called Garmin customer service and they confirmed the Best Buy unit on sale would work for my nuvi 205w so I bought it it.
It works fine.
Here are some of the differences between it and the older one it replaces:
Part number of the new unit is 00239-70. The new unit is slightly shorter, by ¼”, than the original., the pilot light/power up indicator on the new one is a small blue light on the top of the plug-in adapter while on the older model it was a light with a lens that wrapped around from the top to the back end of the plug-in and was thus visible from more angles.. Output specs are stated as a range on the new unit
The fuse will require a wide blade screwdriver or a smallish needle-nose plier used as a 2-prong wrench to replace. A molded in lock on/lock off and an arrow in the tip of the device help with replacement though it would have been helpful if the box containing the new adapter contained a printed instruction sheet for further directions. On the older unit the fuse was replaceable by unscrewing a finger-turnable retention ring. One improvement on the new model – the spring for the fuse, way down at the bottom of the fuse channel, seems to have been given some sort of retention so it does not shoot out unexpectedly and get lost somewhere in the room when the fuse is removed. The strain relief on the back end of the adapter has been redesigned – for the better it seems – it is not as rigid as the one on the older unit. The strain relief at the USB plug end however is only slightly redesigned from the prior failure-prone design and may eventually facilitate power cable breakage when the plastic hardens with age, as did the original.
But, to repeat the new unit. P/N 00239-70, works fine – the nuvi 205w is back in operation and I’ve used the vehicle power cable to power it on several trips into the city and back.
