Question about Garmin Nuvi 660 GPS Receiver
Unfortunately the battery in the nuvi 660, like most garmin satnavs, is not user replaceable. To have it replaced it needs to be sent to garmin. Garmin contact details can be found at http://www.garmin.com/garmin/cms/site/us/support/supportcontact

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.

I read that the front cover around the screen can be pried off, this must be removed to gain access to battery, I would suggest a thin piece of rigid plastic as it will no damage the cover and body edges. Hope this helps

Garmin NUVI 660 instructions
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.

I sat on the phone for 30 minutes waiting for Garmin support when my Nuvi suddenly had no touch screen response. They had me delete a file on the device (with it hooked to my computer) then reboot and it went thru a touch screen alignment and it worked.
Sadly, it has frozen again and I don't recall the file (it had been a GCD file in all caps, that is all I know and I don't see a file in all caps any more). I will be calling support tomorrow.
My take is that it *is* a firmware thing *and* there is some way to reset the firmware.
