06 TR4 4WD Sport: I want to add oem navi system do I need oem JBL amp & sub as well as the navi unti? If so I found one for a : 2003-2005 and my TR4 is an 06? Will it work and do I really need it before the navi itself? If I need it is really hard to install and do I need new plastic interior parts and brackets and stuff for install in the back, do I need to run wires all through and is there a kit I can get or is there a thread. Please help if possible. Thanks
