Sam is 5 years old...his older brother Tom is 3 times as old as Sam...when Sam is old will Tom be?

Well, Tom is 3 x 5 = 15 yrs now. Sam has 15 yrs to go to 20. Then Tom will be 15 + 5 = 30 yrs.

Or, Tom is 10 yrs older than Sam now, so when Sam is 20........

How often should my gps be reset if at all?

The only thing you need to do (maybe) is to update the maps. make sure its maps cover the region where you will be travelling, otherwise it won't be of any help.

Navman problem

WHY is it suddenly, overnight, my Navman EZY 45 has gone from working perfectly to the touch screen hardly working at all? All the buttons have moved ie: You CAN'T touch on the button you want, you need to touch either the one above or below it. As for the Accept and address buttons, well that's just not happening, back = Q and so on.
I have formatted, reloaded maps, done everything Navman has suggested. Is this a Hardware issue? If so, a rarely used 15 month old unit will be going in the bin and I will compare other brands.
Any help appreciated as I love this small but great unit.

My husband received the Garmin Nuvi 465T as a gift, he is an over-the road trucker, and the manual he received is just in Spanish, he cannot read it and is wondering if there is a way in wich he can input...

You can download the English manual from here:
It also contains contact information (p 42).

As for entering directions: A way to achieve this may be to enter the destination, let the device calculate a route and if it deviates from the suggested route in a critical way, add additional stops (see page 5) along the desired route. But this is just my idea - I have no experience with the device.

Garmin nuvi 1310 blank screen

If it is 24 hours old TAKE IT BACK. There is no reason why anything should be going wrong on a brand new device. Whilke there may be a fix you should never have to do this on a brand new gps. Garmin has an excellent service/support system. Just go the the garmin website and call the toll free support number. Pretty sure they will tell you to take it back as well.

I have a nuvi 200, less than 2 yrs old. Has probkems acquiring satelite. Has GPS sw 2.50b and audio 2.20. Also, where and how much is usb adaptor that fits to left side of unit (special plug in to unit

Acquisition of satellites has been addressed in new firmware / system software updates for the Garmin Nuvi 200W.

The usb cable you require is a standard USB to mini-USB cable. MP3 or camera cables will work.

There are three steps to take to get your Nuvi running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin WebUpdater to replace its firmware / system software.

I hope that helps.

Nuvi 200 series manuals available here.
