I own an Argus(DOM June 08)....shoulda got a CYPRES....3 months after installing the Argus in my Wings, the Display unit failed....displays an INK SPOT!....Tried for months to get a replacement with no luck! Finally got an e-mail from Karel Groots indicating he would SELL me a "Ruggedized" unit for $250.00 USD ! If they found it necessary to "RUGGEDIZE" the display units...that tells me the original display units must have been flawed!....I guess I'll bQuoteuy the new display...but I'm not happy about it.......next time I,m going with CYPRES!
