I just test drove a 2010 Journey FWD to replace my 1994 AWD Grand Caravan and am wondering about issues I should be looking for. The car was hit by a deer but only suffered minor damage and the owner will get everything fixed correctly as he has all service records and is very responsive when it comes to this car. It has no rust underneath at all new Michelins struts and shocks replaced and drives well. Is there a replacement Entertainment system that would include Nav that I could put in that would be just a plug n play or do the connector rewire? I have been looking on ebay and there are lots of units. The car has 170 on it but its so clean you would never know it.
