Hi Guys, been away for a while - sorry. Can anyone advise me how to power a Garmin 250w (widescreen) from the bikes power outlet (1200RS)? Is there a cable available? Also what mount would you recommend? I've searched the Ram site but the 250w is not listed. Thanks in advance (Expecting to use the unit in dry-weather riding only - a little un-realistic here in Ireland I know but!!!).
