RB1 Navigation System
I just installed my RB1 Navigation System and the 6-disc remote CD Changer in my '03 3500 Quad Cab.
Yes, you need the changer if you wish to naviagte and listen to CD's at the same time. Be sure to get the CD Changer Installation Kit when you buy the changer as this provides the cable to connect to the head (control) unit.
Installation is very easy, requiring the removal of 1 screw above the accessory hook on the dash panel. The panel then pulls out; it is retained by 6 or 7 spring clips. The existing radio unit is removed by 4 screws. Undo the cable connection and the antenna and it is free and clear. The RB1 requires a GPS antenna (provided) which mounts via an adhesive patch on the plastic air duct behind the radio opening under the dash. Connect the GPS antenna, reconnect the control cable and the radio antenna. If you have installed the 6-disc remote CD Changer, you will connect its cable to the back of the RB1 as well. Slide the RB1 into the opening, replace the 4 screws, snap the dash panel surround back in place and replace the accessory hook screw and you are ready to put the DVD-ROM in and boot up the system!
I love it! I paid $1250 for mine.
I installed the 6-disc CD Changer under the driver's seat with the front facing the door opening. I ran the cable next to the power seat cable; the exisitng hole in the carpet was large enough to accomodate the cable/plug. I then routed the cable along the door sill, up the kick panel, over the instrument panel and into the dash opening for the radio. I only had to remove the door sill trim piece which pulls off as it is secured by 5 or 6 spring clips. The clearance under the seat is fine, though others have mounted the changer in the cubby storage area(s) under the rear seats. Everything worked just fine when I turned it on!
