Not sure about the fit…I think $700.00 is a great deal. I paid $1500.00 for mine new, (898 unit, GPS puck, mount, xducer, wiring) and another $200.00 for the mapping SD card.The only down side for buying used that I can comment on is the warranty.My keypad had issues and I sent my unit back twice to get it replaced.From what I understand the warranty is not transferrable when sold.Its a great unit!!!Last edited by LedzepP4 on January 7th, 2013, 3:10 pm, edited 1 time in total.
