Re: when i plug into car ok but when to mains nothing

First , let me say that the batteries do not fail very often. Answers here to your 3 questions in order ......
1. Your home mains charger is faulty. 2/ Your car charger is probably OK. 3/ Clip out the screen surround. Remove the 4 special STAR screws that are at the corners of the screen. Remove the main circuit board by taking out 4 smaller star screws and let it hang loose but still connected by its cables. DO NOT DISCONNECT THE BOARD CABLES. Remove the speaker . Under the speaker are 2 more screws holding a plastic bracket that clamps the battery. Remove these 2 screws and the battery clip comes off. Unplug the battery cable from the now loose main board and the battery can be removed. Fit new battery and reassemble in reverse order. NOTE , some tomtom 300's have a protective copper or foil sheild covering the main board. The screws holding the board cannot be seen until the foil is removed. Removing this foil and not repalcing it will render your tomtom more prone to interference although the tomtom will still work without it.

I have a manual for the MyGuide 3000GO, but the maps are very old. Is there any way to get updates?

Hello, there are actually two ways to do this.
1. Ensure that your manual allows you to do upgrades 2. Either go to the manufacturer website and download new maps 3. Or, you can update the GPS through your system settings right on the GPS device.

Am holidaying in spain, have hired a c max and do not think the 12v lighter supply is working so sat Nav wont recharge. is there a switch or key position i'm missing as have not driven a c max previously....

Hi, their is no switch or key to get it working, on this car it should start working as soon as you turn the ignition on so as your driving it should be charging.

the only reasons it may not be working could be a fuse or some one may have shorted it out by leaving the cig lighter down to long.

have a look in the glove box and see if the owners handbook is in their if it is have a look in their at the fuse box diagram and locate the fuse for the aux cig lighter then check if the fuse has blown, if it has blown their should be a spare fuse in the fuse box and it should tell you this in the owners handbook,
if how ever the fuse is ok then this means some one has shorted the lighter out and the only way of getting it working is to get the main part replaced and as this is higher car its something you wont be doing.

i would check the fuse and if its blown put the spare in or if their is no spare then it would be worth buying one as they cost next to nothing to buy.

let me know how you get on or if you need further assistance ok

Few reasons this may occur, most you can do something about.

1) Make sure the battery is fully charged before commencing journey ( USB or mains charger)
2) Plug the GPS in after the engine is started to protect the delicate SIIRF chip.NEVER Start engine with GPS connected.
3) Ensure you have a clear uninterrupted view ofd the sky. Place the GPS closer to the windscreen if poss and away from Phone..stereo or other electronic devices

4) If your unit supports it get an external antenna to plug in ( magnetic base mouse antenna)

5) check BAUD and PORT are set correctly.

I have fixed my son's unit twice with the same problem ove the last 18 months.
First remove the 4 screws from the corner on the back.
Then gently pry the back off being careful of the speaker wires attached to the main board.
You can't miss the battery as it's the biggest thing there. Follow the wires to the plug which will probably be hidden under a piece of black tape. Unplug the battery and let it stand for 10 minutes. Plug the battery back in and reassemble!

Tomtom300 gps mains charging +

1= My battery is flat, but when i put it on charge in the house it doesnt charge and no green light comes on, on my sat nav why would this be?

Could be your house charger is bad or the power connector on the back of the Tomtom is bad.

2= But when i put it in car charge it works perfect 'Y'?

You are using the "power shoe" to charge the battery. For a test unplug the power cord from the power shoe and hook it to the back of the Tomtom. If this work then the house charger is bad. If this doesn't work then the Tomtom rear power connector is bad

3= If ever i have to change battery how is this done?

You will have to remove the faceplate and disassemble the Tomtom in order to get to the battery. Or you can find a shop that repairs small electronic. Find the battery on Ebay.
