thanks a lot. I have found a method of working with this. use it as a navigator on the cradle for a few days. plug it and 2 out of 10 times, it gets recongnised. So, I have left it at it. The problem with Garmin is they simply ask me to send it to Taiwan, and the repair cost estimate is close to 220 US$. for that price, I can possibly get a nuvi that even speaks the street names. Guess, i will get used to this. However, I would b checking this page off and on to see if sumthing can b done to make good this error.
