For Garmin Nuvi 255T 255W 255WT 260 260W 295W 1695 GPS Premium Car Charger (No PC or Sleep mode during charging.)
I bought this for my Garmin Nuvi 255W and a spare vehicle.  I plugged it in and it went STRAIGHT to DATA mode then cycles.  Waist of money.  Also Tried it on my Nuvi 1490 with the same results.
