I just bought a 2008 LR2 and I want to update the radio unit to one with nav and satellite radio. Anyone have a good choice for this and is it hard to do on your own? Not sure where the best place is to look. Crutchfield doesnt have any research for the LR2. Thanks. Hope to love my new LR2. Replaced a 05 Jeep GC with the 5.7 Hemi limited and loaded.
