Have just acquired an almost new TE (touring version) of the new LC GS and its likely I'll want to use my Garmin 550 for a while, partly to ease the pain of acquisition and partly cos its taken me so long to get used to the nooks and crannies of the 550 I'm not anxious to start afresh with a new model. The TE comes fitted with a base connector for the Navigator which is (I think) the 660 by another name and I will need to remove that to fit the base connector for the 550. The means of power connection for the latter is fiddly but clear. The connection for the Navigator is concealed and I'm not sure how to get at it. I'm assuming I can disconnect and then tape the cable out of the way till needed while I fit a hard wired connection from the battery to the unit. Does anyone know how I get at the existing cable connection?
