Nothing except instructions would be my preference. No sirf, no globalsat, no gps If you have to have anything "625XT" would be palatable. For colours the red , looks good, so does black so does grey. I think I would like mine to be the black and red colour as per photos. Those other colours, not good.
I agree with Longjog- the round corners look a little strange together with the down border in the display. Shortening the border with 1 mm on each side could do the trick. Bragging about SirfIV is good. The GSSport-logo however is not that good looking though and I miss the product ID. I think, as others have mentioned before, that you should benefit from the name globalsat rather than the unknown gssport but...if you need a symbol that customers can learn to relate to, how about just just using the "G" and the prduct ID "625XT"? Part from that I would (as always) suggest larger figures (numbers) in the display. :-)
Edit: My 615 has G-sat on the front. i like.
Thanks for input.
Our company policy is tending to use G-Sport for sport product which was powered by Globalsat.
After checked with mechanical engineer, they told me to keep good water resistance performance, it was not recommended to reduce the width of rounded corner.
Do you mean to write "GPS SirFStarIV" instead current and enlarge font size of display?
