My charger blew after 5 weeks use, so looks like something failed inside it. I am just setting off for Germany and Austria, I will be able to report on the length of battery life between mains powered recharges in a couple of weeks. |

Further to my previous post, I am assuming that something did go wrong in the charger and that it had not been putting out 12v all the time and that after 5 weeks the Go had had enough and gave up!!!!! |

Have just received a reply from TomTom tech support, they say they are not aware of any problems with the in car charger. I'm off out to buy a multimeter.

I think what they mean is "we know of no general problem with car chargers". They certainly know of 2 specific problems, coz they have replaced GOs under warranty after being fried by faulty chargers.
I guess what we all want to know is - were these simply 2 isolated problems - dealt with by TomTom as all other isolated problems are? Or is there a bigger problem waiting to bite us?
It strikes me that without this forum I would never have found out about IWs problem and I would not be at all concerned. Now I am aware, I check my car charger before I plug it into my GO. |

You're checking it every time? Surely if it's ok to start with it will stay that way??

I think your all worrying un-necessary. There's only two user's that have had a problem, out of how many sold?
If hundereds of users had a fault like this, then yes, TomTom should issue a re-call for the affected models. |

delboy0754 is right of course -
However two points
1. IWs unit failed after 5 weeks use. Something broke inside.
2. We only know of 2 incidences. How many people with GOs read/use this forum. How many of them have reorted their charger failures. We just don't know.
Even my massively over-cautious approach won't help if the failure happens when the charger is on load - which is most likely anyway. I'll probably check for a week or so, get bored, forget and nothing bad will happen. |

Guys, not sure if this helps you but since I own quite a bit of iPAQ gear I didn't even unpack the GO's chrgers, both mains and car charger. I simply continued to use my iPAQ chargers. They also provide 5V at 2A, and they are proven to work, since years ;-) The plug is exactly the same, too. _________________ Lutz

|
|
I bought a TomTom GO from Amazon, which arrived on Monday 4th October, along with 2 extra sets which I hadn't ordered! Whilst I planned to send the two surplus units back to Amazon, it was just as well they'd sent extra, because the first two units I tried went pop and failed to respond after being connected to the car charger on the cradle. :o
I've sent the others back to Amazon, and I'm not going to connect the third (and still working) unit to the car charger until I understand a bit more about why this is happening. I'm very happy with the batter performance anyway, and the unit is meeting expectations in all other ways.
All three units I received had a car adapter that looks exactly the same. Maybe the earlier posts are correct in that there is a dodgy batch of adapters going around. It will be interesting to see if TomTom respond to the increasing numbers of dead units being sent back and offer replacement adapters.  |

Mine still seems OK. The only "unique" mark on it is the QC Pass No, which is 2 or Z in my case. None of the other numbers look like a serial or batch number, so it's going to be difficult to tell if it's a general design fault or just a bad batch. |

I don't think it's the GO you need to look into, it feels more like the car charger is the culprit. Any numbers on that one? _________________ Lutz

The "QC Pass No" is an oval paper sticker on the car charger, mine is also 2, hand-written. |

|
|
I have found that simply pressing the eject/release button and then letting go as I click the TTGO into the mount avoids that awful "crack" sound when it finds the back of the mount. I reckon that will extend it's life a bit longer too and stop it having to be pressed down hard. |

Now, here's a strange one! Look's like the possibility expressed earlier by Dave that it might be the TTG frying the 12v charger could be right, if overload protection in a mains PSU was activated! ... |
