When the ignition is off its likely its drawing power from the tomtom battery - with the ignition on it may be getting a small amount of voltage from the car cigarette lighter to make it run from there, but not enough to power it properly.
I'd suggest replacing/seeing if you can borrow one of the car charger leads to see if that makes any difference. If not it may be in an issue with your cigarette lighter output in the car which can be checked by your local autoshop.
Hope this helps.

Head lights, interior lights all work. I turn the ignition and everything goes out but as I release the turn they come back on. I checked the fuses replaced the ignition main fuse still have this problem.

Clean the battery terminals, may be a bad connection or the battery is flat.
If you take the terminals off, take off the earth (-) one first and put it on last, this will prevent any shorts that may cause some damage. Use hot water and maybe a little washing soda to clean the terminals. Make sure that none goes into the battery.

I ran a small tire pump from the ciarette lighter, it pumped some then stopped.Now the cig lighter doesnt work. My neighbor offered to help . his car did the same thing. I checked the fuse under the dash...

Try replacing the fuse with another of the same size eg 10amp. While you are under there check other fuses. The label is not always correct on Australian Toyotas, could be the same in your country.
If the fuse is blown, there is a short in the pump. Throw it away as it has blown the fuses in both vehicles. (yours and the neighbors)
Next time you are at a spare parts supplier buy yourself a cheap (usually under $10.00) LED computer safe test light. These are easy to use. It has a earth lead with a clip on the end and a probe on the other end that you touch to the fuse and see if it lights up the LED bulb.
First you connect the earth lead to a good earth, the ignition key while in the ignition is usually a good earth or a bolt that goes into the vehciles body. (You need a good earth)
Then you just touch the probe end to one side of the fuse and see if it lights up. If not you touch the other end of the same fuse and it should light up.
If only one end is lighting up the testers bulb the fuse is broken. (Yes it can look fine but be still broken)
If both ends don't light up move the earth lead to a bolt on the vehicle and recheck also check other fuses to make sure your have a good earth.
Tip, Some fuses only work with the ignition turned on while other work all the time.
You can also check the cig lighter with the test light. after checking the fuse is Ok
Again find a good earth bolt and attach the earth lead and place probe end into centre of empty cig lighter and it should light up the bulb. Becareful to to touch the side at the same time as this is the earth for the cig lighter.

Peugeot 306 stereo won't work when engine is running!!

Is this by any chance the original clarion (peugeot branded) stereo?
If so, try disconnecting the remote control stick from the back.
You may find it solves all your problems...
If not, you may wish to check the earthing of your cd player. It sounds like one of the wires may be earthing, or an earth may become live when you tun the ignition on.

How do I recharge my Tom Tom One?

I talked to TomTom support about recharging. They say that the unit uses more power than it gets, but if you turn the power off while the car is running, it will recharge.
