[TG] [TG11] ST5000+. NO DATA error.

Tom, thanks for your good reply. I've been unable to login for a while and have just seen it. Now we are locked down in NZ and I can't get on to the boat!!

I'll check the points you raised re electrical interface, with the vendor if necessary.

In the meantime I've noticed one difference in a Polstar GPS (that does work), and iSailor.
One of the sentences RMC has two new fields (mode and precision. 'A,S' ) at the end. Are these ignored by the ST5000+ or could these be the problem??

----------------------------------------------------------------------------------------

From iSailor- note the last 'A,S' - two extra fields that the Polstar does not send.
$MARMC,000532.39,A,3649.13831,S,17445.94387,E,0.00,33.4,240320,,E,A,S*6D

From Polstar GPS receiver, the following DOES work
