USB port bad

hi,

Please try to charge your unit using both the AC adapter and the Cigarette Lighter Adapter. If only one fails to work then that accessory needs to be replaced

If both fail to work, then the unit requires repairs, please click here , click on "Support/Repair Request", then login and complete the form for assistance.

hope this helps, thanks for using Fixya!

sadly, i havent seen a usb port on a gps that has not ripped the tracers off the board, making a repair, impractical.
have you looked at the board to verifiy it can be repaired, if so, i might be able to lead you in the right direction to aquire 1 ...btw, doesnt this model (4250) also have the standard round female power port?
