I replaced our C90 MFD with the Axiom 9 RV over a year ago and have been impressed with its performance and reliability
. What I do not like is that the access to the micro SD card containing the charts
is on the back of the unit. Because of that, I have to remove the whole unit in order to update the charts
. On the Pro, it is accessible from the front just like the C90 was. In the end, I decided not to pay double the cost for that convenience and installed our unit so that it can be removed without too much trouble. The touch only has given me no problems as of yet. We have back up systems just in case.
