Navman Tracker 5500 signal boosting?

[jamesg999]

I am having problems wih my navman tracker 5500. the signal dies everytime a cloud goes over or if it is placed in front of the screen.

is there anyway of boosting the signal with a extra ariel or something like that?
i have searched on the internet and i cant find anything.

thanks for your help

Sounds like you've either got a bad connection somewhere which is degrading the signal, or there is some strong source of interference on board whichis affecting reception.

Putting an aerial next to other electronic equipment can affect its performance. It certainly shouldn't be mounted at the same level as a radar dome for example.

Hi,

Need a little more info. Where is the antenna? Where is the head unit?

Is it the unit with the internal antenna?

Not sure what you mean by: or if it is placed in front of the screen.

Have you checked the voltage to the unit. Should be an absolute minimum of 12. Probably more like 14 when the engine is running.

If you are stationery, with the engine off, is it OK?

the antenna is built into the gps. the whole thing is placed on the helm. i dont think there could be any interference because there the only 2 electrical items, the radio and the cd player.

sometimes it may find the satalites after about 10 minutes but loose it again once we get out of the harbour. the connecters seem to be clean.

do you think i should upgrade the card inside. it is dated 1 mar 05?

Try it without the radio and cd player connected to power and see if it makes any difference. To do this, you must disconnect the power source from the back of both, not just turn them off with the on/off button. This will rule out any possibility of interference first.

Or, if you can, run it from an entirely seperate power source, such as a burglar alarm battery.

My 5500 acquires in about a minute.

The date on the card won't make any difference.

It looks very much like a power problem.
