Having installed a New EVERMOR Smart GPS receiver I cannot now get the SILVA S15 VHF to recognise the signal or display position. The output from the GPS is well within the NMEA0183 and RS232 parameters and the Silva S15 paper work suggest that there is/was a known potential problem when connecting a new GPS. My Raymarine C80 is able to see the signal via a multiplexer and I have tried connecting the radio via the same but no joy. Also tried direct connection on it's own also no joy. SILVA have given me a routine to reset the radio but that has not solved the problem.

Are you hearing very close traffic or nothing at all?

Antenna is suspect.

Any dead pixels on the screen are an indication of a defective LCD display. The display must be replaced.

Hi Robert,
try the webupdater and update the GPSChipsetTypeG.
It will solve your problem.
I hope it can help You!

Kind regards,

Silva.

Hi,
use the webupdater and replace GPSChipsetTypeG file.

If you shut the unit down - and remove it from the power cord in your car, this is expected.

When powered down, the unit is not capable of maintaining contact with the satellites in the sky. When you power it up, it needs to receive signals from 3 or more satellites get a "fix" or calculate your position in the world. The more signals received, the the more accurately displayed your position will be. The device must use the signal data, perform calculations and bring up a map of your area.

The "Lost Satellite Reception" message also occurs whenever the GPS does not have a clear view of the sky over the earth's equator. This can be from a garage roof to heavy foliage (tree cover) - and even when driving between tall buildings. Usually, it shouldn't take more than a minute or so (once the obstructions have been cleared) for the GPS to reacquire the signals, calculate and display your new position.

I hope this helps!

Hi!

From the S15 owners manual (Page 46):
http://www.bluemoment.com/manuals/silva_s15.pdf

The RED wire is GPS data,
The green wire is GPS ground.

Hope this helps and good luck!

Using the nmea output from your GP-31 to the nmea input on the VHF. Enable the GLL Sentence and make sure the port is set for nmea0183. Remember hooking nmea up it's positive to positive and neg to neg. Once that is done and you have a fix you should have lat and long on your vhf.

See below:

GPS RECEIVER LEAD
Connects to a GPS receiver for position indication.
• An NMEA0183 ver. 2.0 or 3.01 (sentence formatters RMC, GGA,
GNS, GLL) compatible GPS receiver is required. Ask your dealer
about suitable GPS receivers.

Color code:

Yellow: NMEA IN (+)
Green: NMEA IN ( )

Check the wiring again. Installing my M422 needed to switch the polarity of the NEMA input from my GPS75. May be similar problem

Hi wnysoccerdad,

It appears that the manual for the Silva Outdoor Computer can be found on the manufacturer's website at this link.
