over the past several years i've progressed through the core hb units (597ci, 798csi, 998csi, 1198csi), and i recently got into the helix 12si this year.
the increased processor speed of the helix 12 is certainly noticeable (which is a good thing).
however, i'm finally thinking about making the jump to onix (for increased screen customization and map sharing between multiple onix units).
one of the reasons i've stuck with hb is the level of customer support and software updates.
the onix units have been on the market since 2014.
as i shop around and look at both used and new onix 10 units, on the outside they all "look" the same.
but i'm curious if there are any internal changes to the hardware (processor speed and ram memory for example) or major software OS changes (beyond the download-able software updates) through the years.
for example:
new units have the "cross touch" logo printed on the SD card door, but older units do not.
(excluding the NT "no touch" units, as i'm not interested in that model. i want the touch screen feature.)
are the older 2014-2015 units still capable of this "cross touch" multi finger gesture feature?
i'd like to think that an older 2014 unit could be updated to the same specs as a new 2016 unit (with a simple software update, downloaded from the myhumminbird website). but i'm not sure.
perhaps someone who is familiar with the onix product line could help answer these questions (maybe greg or ricky).
