My Garmin Nuvi is ok when it's cloudy but on bright clear days it sometimes takes ages to find a satellite, especially if I haven't used it for a few weeks.

If you can't see the light at the end of the tunnel, just keep going till you go round the bend.
I use a Navman 320 (mine)and a tom tom 1 from work,many times I set both of them for my job I find the Navman takes a while to put in the address or post code as I have to go around the key pad, the Tom TOM is quicker as I just have to touch the screen, The Navman talks to me at all junctions ,left right straight on , BUT the Tom Tom just lets me go straight until I reach the next turning point,
So I would like the ease of the Tom Tom for loading ,with the directions of the Navman I think if I change my own I would have a better Navman with touch screen, but as we all say we all like different things,
Dependant on what model etrex your using and what for they are a pretty good model. The only time I've known one not to get any sat lock at all due to cloud cover was during extremly sever cloud cover, and even the GPS cradle for my PDA lost the signal as well.
You have to remember the almanac has to be up to date to enable it to search for the satellites, if it's not been used for 3-4 weeks then the almanac [it's a sort of record of where to expect each satellite at a particular time on any day] will be out of date and the unit will have to find a signal from at least one and download it [this can take from a few minutes to up to half a hour. And is best accomplished in a area with a clear view of the sky all around .
Also make sure you've got fresh batteries loaded, if your using rechargable make sure their freshly charged. As low power can affect the units ability to find a signal.
Remember the etrex is designed as a land/sea navigation unit and not a road navigation such as units with Tom Tom are designed to do. You don't use a Thoroughbred to pull a plough. Just like you cant rely on a Tom Tom unit to take you up a mountain on footpaths, don't rely on a mapping etrex to be as good at road routing as a Tom Tom.Also if you've got a thermal windscreen this can block the signal as well.
The above comes from hours of use with a Yellow [basic] Etrex and includes several thousand road miles, just following the arrow as it's not a mapping unit. Current cost for one is about £60 unless you get the H model which copes with tree cover far better at about £80. you'll pay more for a Tom Tom, which if your not careful will route you down farm tracks as it thinks it's a proper road. So much for being better

I have used quite a few different Sat Navs, had 3 myself and another 3 in work. Tom Tom is the only one I have ever seen get a signal indoors. Now if Sky could get a satellite receiver to work without a dish I would be impressed. (I have read that the old BSB "squariel" would work through a roof from an attic)
