change of battery charging point ?

I have TomTom ONE XL type gps. The original holder is not a good designed part of system, and it has not been able to hold the gps, and it fell down several times. This caused the damage of battery charging point on the bottom of the gps. I have been trying to get it mended, but in Hungary impossible to buy the mentioned bodypart, and furthermore there is no a single mark service as well. Could you help me, how can I buy the bodypart? I have a specialist who is able to change it, if I can get one. Tanks for your cooperation.
