Internally , the Rider is very similar to other tomtom models . From what you describe it sounds like your charger has gone faulty ( quite common ) . There is a sensing wire that goes from the charger to the plug tip to check the voltage is at 5v . If this sense wire becomes detached or broken then the charger will increase the voltage and unfortunalely , in turn fries 2 chips inside your TomTom . ( these are numbers U24 and U25 in most tomtoms ) . Its not possible for a standard electronics technician to repair these as it need someone experienced with these tiny components and also requires use of special tools and soldering techniques. You will have to have it repaired by either TomTom or a suitable TomTom repair centre . Even then , if the blown chips have got really hot then it's possible they have burnt the circuit board tracks and in this case a repair isn't possible. Throw the existing charger away as if you do get it repaired plugging that one in could easily cause your TomTom to blow again. You can check the voltage output of your charger using a multimeter which would probably confirm what I say above . Sorry to be barer of bad news.... Good Luck
Hi , Its likely you have a faulty charger putting too much voltage out , or , your car cigarette charger socket is dirty or similar causing intermittent supply and resulting in voltage spikes going through the charger and into the TomTom .... or ... spikes caused when starting your car whilst the charger is plugged in. The tomtoms are very sensitive to any overvoltage and it blows 2 IC's inside the TomTom. The car chargers are also known to put out overvoltage when they go faulty , it's quite common. Some car alternators dont regulate their voltage very well at the point of starting the engine so it's probably worth having this checked by an auto electrician. Cranking the engine cna also cause the starter motor to act like a generator just at the point where the engine fires and this then results in a voltage comming back out of the starter motor and into the cars wiring. Your TomTom charger should cope with this but it is possible that any spikes manage to get past the charger and into the tomtom. if you have had one TomTom blow using any particualr charger unit , then don't risk using that charger on a different TomTom uless you have that charger checked for correct voltage.
For the guest comment .............. The Blue Tooth will not have caused the problem you are reporting , thats just a coincidence. The problems of having buttons highlight themselves and the touch screen not working properly is a fault with the membrain on the tomtom screen . Could be a fault on the membrain or just dust and dirt particles trapped under and around edge of the screen bezel ( plastic screen surround ). Try clipping out the bezel and see if theres any dirt around edges of screen . If there is , be careful how you clean that dirt / dust out. ... Good luck
Most likey its not worth fixing. Look at it like this. While it may have only been 6 volts versus 5. One volt in a 5 volt system is a 20 percent increase.
If you took something that ran on 120 volts and plugged it into a 144 volt source you can figure the damage that would do.
First , try a re-set through the 'reset' hole underneath the tomtom. 1 quick short press is all thats required. Unlike others suggest , you do not need to hold it in for anything longer than half a second. You should feel the switch 'click' as its a tactile switch. Don't press too hard as you can damage the switch and cause it to lock ON. Once pressed , try turning the tomtom on as normal. Sometimes a tomtom battery can drop below its normal "shelf" voltage ( normal is about 3.8 volts ). A tomtom charger has a protection circuit inside to stop or slow the current it gives out if there is a short. If your battery HAS dropped volts TOO MUCH ( less than 3 volts ) the charger can "see" the tomtom battery as a "short" and the charger therefore shuts down and doesnt charge the battery. You could leave the charger connected and HOPE that the very small amount of current it's putting out will eventualy bring the battery up over 3 volts. Once it is up near its "shelf" voltage ( called shelf voltage as that is the voltage the battery is at 'on the shelf' ie . when its not powering anything ) the charger will begin to charge as normal....... OR ... you can gain access to the battery and charge it from a bench power supply that has voltage and current meters. Once again , once the battery voltage gets something near 3.8 volts the normal tomtom charger can be used to charge it. You caould connect another normal battery to the tomtom battery just for a few seconds ( not recommended and can be a bit dangerous ) if the normal battery is such as a PP3 9v type it should bring up the tomtom battery to over 3.8 volts in a few seconds. The tomtom can then be charged as normal. .............. It is also possible that some internal IC's ( chips ) have blown inside the tomtom and unfortunatly this would require a specialist repair centre to replace them as they are really very very small and are not a normal soldering job. Good luck. ... if this post has helped you or interested you please rate the author.
The roadmate operates on five volts dc. Look at the back of the unit and it says so there. Inside the cig lighter plug that comes with the roadmate 2000 is a transformer that converts 12 v dc to five v dc. You used the wrong charger and put twelve volts across a unit that only handles and requires five volts.
Check to be sure that you used the correct charger. it sounds like you did not. It may be possible that the charger was still wet or was damaged when wet and that it shorted out.
Radio shack sells a charger for the car that is made for magellin roadmate 2ooo. It includes several different tips including the one that fits this gps unit and the output is five v dc. It is possible that what you smelled was the charger cord and not the gps unit itself.
I used the wrong charger on mine and had a similar problem. I bought this charger and all is well. radio shack cat no is 20-151. Get it soon because it is on sale for about thirteen dollars and is discontinued. As of today, sat jan 12, 2008 they still have them in stock at most stores. You can call ahead or look online and it will even tell you which stores have them, or you can order online as well.
No, if it is the gps unit titself, do not try to mess w the circuit board. Its cheaper to buy a new one. good luck to all w similar problems and ALLWAYS check to see that voltage and ac or dc symbols, as well as polarity, match up. If not bring your electronics to radio shack Before powering up and they can check all of this ffor free if you are unsure.
