    Unhappy Globalsat BU303 sat lock

    Hello all.
    Installed car pc ok, but sat nav unreliable. The BU303 keeps loosing sat lock for long periods of time, but when it does lock on I get up tp 10 sats showing.
    I read some months ago of a simular problem that was traced to a dead batery inside the BU 303, which when removed cured the problem. I have searched but cannot find the thread. Can anyone help with the problem or point me to the the thread......Many thanks.

    Having read the thread to the end, I am more confused than ever
    Should I remove the supercap or not? Is this likely to cure the problem I am experiencing? Can anyone recommend an alternative that will work reliably?
    Please, please, help!!!!!!!!!!

    Try removing the supercap and see if things improve. Somehow I believe that many problems people are having with their BU-303 are because of the housing not being waterproof.

    I have my BU-303 on the inside back window no tint. It works fine but then it will lose all the sats and I get lost and then way later it will pickup.

    Same results outside the car

    brand new today ?

    what do I do?

    thanks

    Try changing the refresh rate of your LCD. Anything above 70Hz makes mine lose locks (if it even manages to get one). Below that it works fine!

    Really. I think raising tire pressure and topping off the coolant would fix the problem.
    Is this where the witty comment goes?

    Have you got one?

    It actually makes perfect sense if you know anything about electronics & RF interference.

    Do some research before you post, i'm not the only one that had this problem and - IT WORKS! Can be replicated over and over again, change rate - lose lock, change back & get lock again!

    bu-303 ... noticed something

    What can cause radio interference with GPS signals?
