I have a nuvi 765T gps, and can not read the screen on sunny days. A bud has the 5" 1490T, and the screen was bright enough to read in bright sunlight. Before I drop more money on a gps, how bright is the zumo 660 screen? Can you easily read the map on bright sunny days?

 

I have no problem reading my 660 in daylight.

 

Have you tried switching it to night? The black background is easier to see and about $500 cheaper.

 

big e78, I tried changing the mode settings.

 

I just bought a 765T and found if it's plugged in it is brighter. Mines seems to be working fine in bright sunlight. Like the fact that I can have the MP3 player playing my songs and have my phone sync'd up to it and the GPS is breaking in and telling me when to make a turn. I also have it in the AUX jack on my radio,

 

Do you have a cable going right from the GPS into the AUX jack? I'm thinking of doing this with a 755. If you have it into the aux will the voice prompts come through the intercom if you're listening to either the radio or CD? Thanks

 

I've got a 765T. Get a glarestomper and it'll help you out. Then use the night mode and no real issues for me anyway.
