I took my 04 LT out for a ride Thursday after doing the following: Sending radio out for amp upgrade and Aux install with Baris. Changing coolant, changing air filter, changing fuel filter. Changing spark plugs. Installed J&M CB.And installed a Garmin zumo 550.Radio sounds fantastic.She rides, runs great. Question is .I'm having trouble loading music in the 550.And music that is in there I can't pull up on the unit, but shows up on the laptop when plugged in. Any thoughts??
