I recently replaced the standard (Garmin?) GPS in my FL2 with a Hema HN5i.

It's a brilliant - cow.
If I can get the reversing camera working on the standard GPS, I might put it back in.
Pros:
* Street navigation is good - probably better than the Garmin. Better definitely than the Garmin I've put in the wife's Jazz. Speed limit warning has probably half-paid for it.
* Off-road navigation is OK - basically 1:100,000 maps, magnfied - with 'where have I been?' auto-tracking for a couple of days. With speed of travel tracking (more accurate than the speedo) it's also good for daily use in non-off-road rural driving.
* third function - haven't used much - but you can download many maps and do really detailed super-remote planning.
* reversing camera compatible
Cons:
* It can't be linked to the ignition for automatic turn-on/turn-off.
* The on-off switch is mounted on top, so it can't be mounted permanently in the GPS slot in the dash. If only it was in front!
# will I have to drill a hole in my dash?
* in Street mode, it turns itself off, after a time. (Then one has to finangle and turn it on again).
* In 4WD mode, it never turns itself off, and (theoretically) flattens batteries.
** so much for automatic reversing camera!!!
* it takes forever to fire up
# to be fair, the reversing camera will come on before the GPS is active as a GPS
* changing from 4WD to Street takes a lot of time - processing. It gets there, eventually, but not conveniently.

Summary? Probably the best 3-function GPS (with camera-screen) on the market - as an ex-dash mount. AND! in need of some serious further development/de-bugging for in-dash permanent mounting!!

I love it and grind my teeth both.
