Question about Magellan RoadMate 700 GPS Receiver

1 Answer

No sound Hi Dan, My unit has zero sound now. It had "scratchy sound" like an old cracked speaker for awhile. Do they make replacement speakers? I did pull the housing apart and looked at the speaker, but did not see any obvious cracks or holes. It works fine except for the sound. Thanks for the help

My Garmin Nuvi660 has stop sound out of the speaker. Sometimes it work for a second. I can't open the unit to see if the speaker is loose.

The speaker is not loose and I would advise not to open it up. Your speaker has an intermittent voice coil. The speaker needs to be replaced.

Please see this link. Too much info to be pasted here.

The sound on my garmin zumo 550 is not working right it has been working fine. But this morning when I hooked it to my Harley ultra classic it was reel low upon further check it was only coming through...

sounds like the Audio patch cord, i had around 5 of them that do that ...sometimes i hear the music thru one speaker, cracking noise sometimes it works when the wire is twisted, but i would try a new patch cord patch cord worked fine on some stereo units others break up

Low foice volume

Hi, Most likely cause is a faulty speaker ( quite common ) . if its a tomtom one then it could also be the earphone socket. The socket is also a switch that turns off the internal speaker when a plug is conencted and sometimes the contacts become dirty resulting in crackly sound , no sound or low volume. Cures are 1/ replace speaker . 2/ clean socket. note : people who sell scrap laptop parts often also have speakers out of the laptops . these make a suitable replacement. Check physical sizes though before you purchase anything. One last possible cause is corrupted data on any SD card or internal drive . If you made a backup ( anyone reading this should make a backup NOW ) you could try reinstalling the backup to see if that cures it. ....... GOOD LUCK

The TomTom One is known to have sound problems on some units. The 2 main problems:
  1. The speaker is blown or distorted ( needs replacement ) ( some speakers out of old laptops will fit )
  2. The earphone socket on the base of TomTom is dirty or has bent contacts . ( slightly bent contacts will cause sound to dissapear or become broken-up )

Nuvi 350 blown speaker

When you tap the GPS it is probably doing one of two things:

1. The tapping is temporarily reconnecting the broken voice coil in the speaker (speaker will need to be replaced)

2. The tapping is temporarily reconnecting a bad solder joint from the GPS motherboard to the speaker. (The solder joint will need to be resoldered)

You can either send the unit back for repair or purchase a FM modulator and retrieve the audio through your FM car stereo.

You can purchase an external FM modulator like those used on IPODS and CD players. I am using one on my Nuvi 350 and it works well. Just plug it into the headphone jack. Advice: Be sure to buy one that is crystal (PLL) controlled and NOT using a tuning dial. The FM modulators that use a tuning dial often tend to drift and they will also change frequency when you hit a bump in the road.
If you decide to send it back for repair, be sure to have your serial number handy. Register it online
if you haven't already done so.

No sound

Not the first time I've heard about this one. TomTom is not publicizing this issue, but they will fix it. It seems as though some models have a tendency for their speaker to stop working. You can contact Tom Tom tech support at Talk to a rep. You will have to send your unit to them, and they will either fix it or send you another
