<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Yes this is very possible as i have a customer who just did it on her G2 wagon grand. Your best bet for the how to's and such is Mark Wisner. All electronics are cost prohibitive. More bells and whistles on the newer models so that could be a consideration. What does your customer want to do with it?

I don't think money is an issue. Is this possible? NO, the only thing that you can do is upgrade the controller which will go piggyback on the wagon grand.  You can get better  response, If you buy a newer system, the whole mechanism is better and quieter. Cost prohibitive?  Practically Or should he just trade it in? Better to sell the entire unit. Anyone? Mark? Serial is 4871172 Call Mark Wisner or the people at Yamaha USA for more questions. Thanks!
