I have a 2007 RX 400h. Whenever I receive a phone call from someone's cell phone it shows up on my navigation screen as "Ingrid - cell", which is the tag I have for my wife's number and which is programmed in as the #1 spot on my car's speed dial system. The problem is that the person calling is usually not my wife - it is a friend, a colleague, a parent, etc. calling from their phone. Has anyone else had this problem? Is there a fix? Any ideas/suggestions?
