XM DSC

[Parsonsheath]

I did write earlier about problems getting my Garmin to work with this, thanks for earlier ideas, sadly not worked yet!

While I have got a load of detail from Garmin I have had no joy from the suppliers of the XM.

Has anyone out there got the XM to work with a Garmin 38 or 48? Alternatively does anyone know the "strings" the XM needs to read the NMEA from the gps?

I have a Garmin 128 connected to an XM DSC and it works (nearly all the time).
As far as I remember, the two surprises are:

The Garmin uses its power supply earth as NMEA earth too so the radio's NMEA earth is connected to power earth
The Garmin doesn't talk NMEA until you tell it to (in the Interface menu as I recall). It naturally talks something else called Garmin.

But whether any of the above applies to a Garmin 38 or 48 I can't say I'm afraid.

My XM DSC initially had problems with the Furuno GPS.

The connections were straightforward, but my problem was with the NMEA sentence type.

The Furuno is quite old, and had two sentence types. I initially picked the wrong one! Once that was sorted I have had no problem

I helped a chum recently hook up his DSC with a Garmin. The GPS seemd to have only one type of NMEA sentence, amongst various other types of output. Our problem on my friends boat was the connections!

Hope that is one some help.

the most constructive advice I could honestly give is,

flog the XM on ebay and buy an ICOM or Simrad.

Wouldn't want to think I was relying on an XM VHF in a life & death situation!
