I know this is probably beating a dead horse, but I really don't know the truth !!! I'm looking for a 2970n2 Ranger radio....I know about the E-chip, but I was told today that there was 2 versions of this radio !!! I was told there was a Ranger 2970n2 model and a Ranger 2970n2 export model, I don't know how to distinguish between the 2 models if there is such !!! If any of you can help me out it would be greatly appreciated, Thanks !!!
