Altitude readout?

Do any of the tom-tom models support a readout of altitude?

Reason I ask is that my old Garmin GPS on our boat (comes with option for
fish finder and water temperature...) does give altitude. Whenever it locks
on three or more satellites, it can do 3-axis navigation. Nice except that
the outputs are only Lat/Long; requiring chart reading skills.

My wife has some medical issues that dictate we should stay below 2000 ft.
Travelling through the mountains by road, this sometimes can't be helped.
Just nice to know what the altitude is and not have to keep looking over at
wifey to see if her lips have turned blue... a navigation equivalent of the
canary in the coal mine.

altitude is OK on my GO630

Hallo,

as has been told in an other reply, there are ways to show the altitude.
The question is however, how reliable is that value? I have a TomTom GO
630 and I am logging the NMEA-output of the GPS receiver. There you can
see that the receiver is reporting the elevation and geoid-height. It is
however also reporting the type of satellite fix. This is for me always
a 2D-fix (no 3D-fix). It is also a 2D-fix when I have 8 satellites
fixed. There is also no VDOP reported by the receiver.

This shows that the GPS-received used by the TomTom is only capable of
giving a good 2D-fix. You can't use the elevation.

Regards,
Vincent

Not enough to risk the OP's wife's life on. In my experience altitude
is very unreliable compared to your position on the ground on car
Satnav's, where altitude isn't important for 99.9999999% of consumers.
