Q:I have noticed that the 798 is referred to in two ways, (1)is the 798ci HD SI - (2)is the 798CXI HD SI. Could you tell me what the difference is? Thanks Hank.Asked on 4/3/2014 by Hank from Kitts Hill,Ohio
A:Thank you for your question.
798ci HD SI is the North American Version. 798CXI HD SI is the international versions for markets outside of the USA and Canada. Same unit--Same Performance--just extra language sets in the formatting for non-US markets.Answered on 4/4/2014 by Anonymous
