I never asked but I have read the same thing somewhere else also. I don't mind not having the 7 year warranty, if the GPS goes bad in a year Amazon or Garmin will come good for it. I have had many GPS's in my life and never one thing wrong with them, so no biggie really. I am just glad I don't have to deal with the wiring. If something goes wrong I will buy another one and it will be plug and play with the wires already being there. I will still be about even.From this statement, do you believe you are getting the 7 year warranty on the 50s that the dealer is installing? This was not the case with mine. The 7 year is on factory installed options or options that appear on your build sheet and then dealer installed. It has to be on the build sheet as it came from Bennington. This is why it is more expensive when part of the build...the 7 year warranty.
If the dealer is telling you otherwise, make sure you get it in writing.
