TomTom 720 Faulty Speaker

retrospek · Occasional Visitor Joined: Jul 21, 2005 Posts: 18

Hi all,

I bought a TomTom 720 today.. However, I'm having a problem which makes me think it may have to be returned...

When I put the volume up to 100% I get a really bad crackle from the speaker and the screen gets a bit distorted - almost as if I have an electrical fault.

Also, I fully charged the battery earlier today but the unit only lasted 40 minutes before it switched off because of low battery (I did have Bluetooth on and connected to my phone but would this reduce the battery so much ?)

I assume these faults I'm experiencing are not 'normal' ?

Thanks,
Mark

Get it replaced. There seem to many reports of faults in this new model.

Mine makes the horrible noise at 100% volume also. It's the amp clipping.

Does anyone have a 720 that sounds clear at 100% volume? (You'll need to turn off that dynamic volume option to be sure you're at the maximum.)

Hey Retrospek,

I'm getting the noise from the speaker at high volumes. It doesn't sound like amp clipping to me but actually the speaker looks like it's too small to cope with that volume. I've come from a go 300 and the speaker in that one seemed twice the size. Re: battery life, I got 5 hours before the low battery sign without bluetooth on.
Not sure if i'm taking mine back...although currys would replace after having it just 2 days no questions asked i would think.

Follow up to post above...
Been to Currys...explained problem and the guy tried the "it's the design...." excuse...didn't seem really surprised.
They didn't have anymore in stock so they rang a nearby pcworld and got me a replacement. This one's fine...full volume, no distortion at all...

Just got mine delivered for PCWB today, I've already filled in the online returns form.

Using hands free at max volume the speaker vibrates horendously.
On directions it only vibrates intermittently on max volume.

Not happy.

based on a previous post I've found it is very easily repeated.

Go into volume preferences.
Set volume to 100%
untick 'link volume to noise level'
Select 'Test'

Speaker vibrates like mad, starts vibrating at 90% upwards.

If a couple of other people would be kind enough to try this and let me know the results I'd be grateful.

Tried mine my volume & speaker are ok.
Anyone tried choosing an address by voice recognition I tried mine out. Voice recognition accepts city and street but when it comes to house number like 171 it reads it back as 171 but then says 171 and with a slight pause it adds anothoer number on the end and says 1716 and then adds another number on the end. Called TT help and played it to them while on the phone, he said that shouldn't happen took my email address and said he would get back to me. Even though I have disabled tips, a tip comes up in voice recognition and locks my 720 have to turn it off to get out of it.
Has anyone else had the same

Mine has this distortion fault as well.

In fact mine had so many different faults I have sent it back for a refund.

If I get another one, then I will buy it locally, as I can see these having lots of problems.

Taking it back to a shop is less trouble then posting back to a mail order company several times and waiting for refunds or exchanges.

Hi, when I was in Seattle, I did notice my speaker distorting as many have mentioned. I also noticed that the screen flickered as it distorted. Then I realised that the battery appeared to be low, even though my car charger was plugged into the lighter. Turned out the connection was a bit faulty and I had jiggle the plug abit until the green light indicated charging on the unit. Once the unit was receiving power, my speaker at 100% was fine and the screen no longer flickered. I'm assuming the speaker problem was due to being underpowered? Now my unit is fine at 100% volume. I too was very worried as I had only picked up the unit a few hours before hand. Are you guys having the speaker problem with a fully charged/powered unit?

I'm with technik on this one, there are currently too many faults with the unit to bother with mail order, I've got my returns number and I'm popping the unt back into PCWB this lunchtime for a refund.

Once these initial problems have been solved I'll have another look.

I've used my 720 all this week as I've been having to travel.. Unfortunately, things didn't get any better..

The 720 has hung on me twice during the week. The 720 has switched off when on battery low - however, it didn't warn the battery was low ! also I've still got the speaker problem but it seems to only show itself when on battery power and the power is getting low.

So anyway, I've just taken the 720 back to Curry's and got another one.. Hopefully this one will be better Confused

I'm now on my 3rd unit, the first one kept locking up, the second one had a problem with the speech recognition, it would struggle hearing what was being said,if you said Stroud it would list lots of cities beginning with 'L'. I think the MIC was faulty. The 3rd unit seems OK, it was useful having seen the Speech Recognition working correctly. I've now purchased my unit from Argos just incase this unit develops a faulty.
