Re-Newbie here. I just picked up a 1999 LT with only 14000 miles on it. I had an 03 in 03-04. The 03 was an elite? with all the factory options. The 99 is a lower perhaps base model? In the glove box/cassette box there are 2 very small jacks 2 larger ones like the jack on and iPhone and one knob and a small toggle switch. How do I get an iPhone or mp3 player jacked into the system. Also what is the best way to get an intercom system? Glad to be back on an LT. Thanks for the help.
