Hello: I just found this forum and thought I would check it out. I have had Jeeps for at least 15 years now. At this time I just bought a 2008 Grand Cherokee Limited to replace my very high mile Mercedes ML350. I also have a 2002 Grand Cherokee Limited 4.7 HO that I bought new. This Inferno red Jeep only has 11,200 miles on it . I guess I am keeping for retirement. I have had six other Grand Cherokees, including a 1998 Limited 5.9. I wish I had that one back. I look forward to new info and advise on Jeeps again. I have no clue how all of the features work on the 2008 with the navigation system.
