Question about Garmin GPS
Are the diagnostic menus (accessed from the battery icon)
read only or can you change various parameters such as FM
power output? On one page there is a option to start and
stop playing a selectable phrase but it does not appear to work. Garmin does not comment on this type of question.
This is regarding the Nuvi 760.

Sounds like you both have a battery problem. I experienced a similar problem when trying to charge via the USB-cable connected to my computer.
Ended up buying an original charger (expensive) and the charging went smooth.
The car charger should in any case work fine, so probably your battery is not very healthy.
Try holding your finger on the battery symbol for about 10 sec. The unit will then switch to a technical page. There you can observe the battery and charging voltage. When I plug in my computer USB-cable, I read around 4,4V and that is not sufficient for charging my battery.
When connected to the original charger, this voltage rises to about 5V which gives a nice charge. When unplugging charger, the unit displays the battery capacity. If the charging voltage is OK, but battery capacity drops quickly after you unplug charger cable, the battery is probably bad. (Of course you have to charge is for some time) I think around 4V battery voltage give 100% capacity. 3,9V gives about 90% capacity.
This will not solve your problem, but can give you an idea about what is wrong.

Go back into your tools and settings and re select the voice of american jack and see if it comes back on.
I lost the voice 2 days ago while on a trip from tenn. to florida and this fixed it. we never shut off the voice but somehow while using bluetooth or FM trans it shut off voice transmiting.

Sounds like your speaker went south. Since your fm transmitter is working I'll be your earphone jack is too. So you could always use an earphone. Only other option is a speaker replacement.
