After long dithering I purchased a CP190i as the "indoor" GPS
to back up my much-loved hand-held Garmin
The 190i, unpacked, looks good -- compact, internal antenna
, simple to install. But in reading the manual I've come across something disturbing and not sure I want to install it (and possibly render it unreturnable) without inquiring further.
The disturbing thing is that the page which displays only course and speed info in a huge font [knotmeter page: all the GPS
units I've used offer one or a similar "zoom view" of selected fields, very handy for racing
or sail trim, and visible from the helm] is described in the manual as the "NMEA DATA" page, and the manual implies that this page only displays data from external NMEA
So this seems very odd -- why would a GPS unit need *another* external GPS unit to send it speed data over NMEA
? As fate would have it, the page I *most* want on the internal GPS is a giant easy-to-read knotmeter
What immediately occurs to me -- if this weirdness is actually true and not just a translation or scribal error in the manual -- is to wire the unit's own NMEA send to its receive, trying to fool it into reading its own NMEA output. But I'm not familiar enough with NMEA to know whether I can get away with this (this is my first modern GPS).
If anyone who has a Standard Horizon GPS in this family
can comment on the "NMEA DATA" page and whether it's possible to display the unit's own data, I'd very much like to know before I install it and cut cables
to length :-)
