Not even sure if there is use in posting this, but updating maps from Garmin servers is still as slow as ever. Currently 20 KBs. Compare to downloads from other sites which routinely are done at 1Mbs.
No help to you but my downloads work perfectly well, maybe check with your ISP to see if they throttle the downloads
Yup, never experienced any problems re: slow download speeds from Garmin servers myself either.
