Are we unable to change speed limits on Interstates? I have tried several times to change a speed limit on a short section of I95 but it doesn't make it to the Go 730. I tried making the changes using Home and on the Device. I have tried doing the hard reset but nothing works. I have made changes to speed zones on local roads with no problems but I cannot get this change made to I95. If anyone else would like to try, it is the section of I95 just south of Petersburg, VA between the I95/I295 intersection north past the next 2 exits to the railroad tracks. The speed limit has recently changed from 55 to 65.
