Ok so i have a 05 xtype 3.0 first off it has a 2003 map set and i want to at least upgrade this to current, 2nd it doesn't have the phone option and i would really like to be able to have bluetooth for the wife so my question is there and upgrade for the phone or would i have to put in a whole new stereo/nav and if so is there a model year that is compatible without having to modify anything on the dash? any help would be appreciated
thanks
todd
