So i guess b4 sending it back, I need to paste the original LEX_PGK, delete CXNA, POI, delete all .unl i created etc..

again thanks for all the help. plus i don't think they send me a refurbished since mind only been 2wks. Garmin rep gave me her personal work email so that communication r ez, instead of going to various rep. i already email her the picture of those dot. her reply when she saw the pic
Thank you for the reply. The pictures seem to make the marks look almost like a fine crac.k. Are you able to see the markings when the unit is off too? Does the display have any distortion or discoloration?
my reply
it's not a crac.k. The screen is smooth when feeling it. No distortion nor discoloration. When it's off I hardly see it since the screen is dark. When it's on yes I can see the dot as in the pictures. However, that dot thing, sometime I see it. For instead, last night at home I saw it and able to took pic for you. And now as I'm emailing you, I can't see it. But earlier today, I saw it.

Another thing was before the v7.10 update, my PC, Windows 7, able to find nuvi right away, in a second. Now, it took about a min or so. Plus some time it asks me to scan the nuvi.

Thanks,
