Nuvi 660 won't turn on past initial screen

SOURCE: voice not working properly on garmin nuvi 660 - very disdorted

i have been told that voice to street is not as clear as the voice just stating turns. If it really bothers you then try voice to turn. I cant remember the setting but it should work well for you.

Well , do you delete or add something in your NUVI before that occured.

Need more information.

Is that a new problem ?

I had this problem. I discovered that I was using the wrong lead in the car. The problem resolved itself when I used the lead that came with it.

It is pretty easy to open up your nuvi,(but not recommended by Garmin or me)...
looking at your nuvi from the back flip up the antenna. You will see two tiny torx screws on the antenna. Remove them and carefully seperate the antenna housing. Pay attention to how the antenna flex is seated because reassembling the antenna housing can be tricky. On the left bottom side the pin assembly that holds the antenna in is spring loaded. Pull the pin towards the center and you will be able to seperate the antenna housing from the unit. Underneath you will find two more tiny torx screws holding the main housing togather. Remove those two screws and you are almost home. Now you need the special plastic tool that you can get on ebay. The tool is used for opening ipods without mangling them. Gently pry the case apart with this tool. Start where ever it is easiest to get the tool in. Once opened you can figure the rest out for yourself. The battery is flat and rectangular and is seated behind the circuit bourd attached to the back cover.
