Question about Garmin nuvi 750 GPS Receiver

1 Answer

No car radio / stereo for use with Garmin nuvi 750 GPS

Can the Garmin nuvi 750 GPS's voice prompts be heard if your car does not have a radio / stereo? Can headphones be plugged into the jack to hear the prompts? Does the 750 have an external speaker that will allow the prompts to be heard without headphones, or can the voice prompts for the 750 only be heard through a car radio / stereo?

Every Garmin Nuvi unit I've seen has a (loud) built-in speaker. The only demand our 250s and 265 make of the vehicle is a 12V power supply (and they'll even work without that for a while, until the battery goes flat).

No french laguage

On the Nuvi 7xx series as well as many other nuvi models, voice updates are free and downloadable from Garmin only charges for map upgrades. Maps do not contain voices. I have backups of french text to speech (TTS) voices. I would be happy to give you links to download them to you.

Garmin Nuvi 1390 voice prompt does not work

If your garmin nuvi's voice prompt does not work anymore, then you have to connect it to a system, back up all your files, then you reset or format it, once you have done that, then you restore your maps back on it, then you connect it back to where you took it out from, then you reset the voice prompt. After doing this Your voice prompt should be in good order.

No voice prompts on my new nuvi 750- volume level not muted.

I had the same problem after I had my Nuvi 750 for a few months.  The voice just stopped.  I called Garmin and they replaced it under warranty.
