I feel I should mention that roger is an expert on the Thames Estuary. He has written a really informative book on the Estuary and how to passage plan a route across it. Anyone who sails or intends to sail in the Estuary should read it; its called Crossing the Thames Estuary by Roger Gasper and is published by Imray, the charts people.

Usually when an update is not recognised it is an incorrect version although, of course, it may be something wrong with the SD card or with the files on it. Are you certain that you haven’t got a Mk1 708? Mk2 versions have a serial number beginning 2 e.g KP708219etc will be a mk2 produced in 2019. What update did you load to your SD card and what is your serial number.

Suponiendo que usted tiene un Mk2 versión 1299, el último firmware oficial 1.14.20 que se puede descargar desde el sitio web de Onwa. 19.3.12, no lo reconozco, pero supongo que es la versión del 19 de marzo, que es bastante antigua. Existe la posibilidad de que pierdas la función de head up aunque lo dudo. Si lo hace, tendrá que revertir el firmware a la versión anterior. Onwa debería ser capaz de suministrar eso para usted. Sólo para estar seguro de que no tienes un Mk1 1299, ¿qué edad tiene tu 1299? Los números de serie Mk2 comienzan 12992.
Espero que los españoles en esta respuesta tengan algún sentido -estoy usando al Sr. Google para traducir!

Is your NAVDATA NMEA0183 compatible? Raymarine use their own version of data, SeaTalk, which is not directly compatible with NMEA but there are converters available.

NMEA sentences, I usually select:

APA
APB
RMB
VTG
XTE
BOD

These usually work with auto pilots.

Connections are usually the problem and if still no good, you should refer to your 708A manual for the correct NMEA out connections. One other possibility, if you are sharing the NMEA output with anything else you may be dragging the data signal down. Only one device should be connected to your 708A NMEA output – use an NMEA distribution box if this is the problem.

Are you sure it isn’t an antenna problem as in most cases poor reception/transmission is down to the antenna and I have never had a case of poor reception on a 1299A that wasn’t the antenna. I would suggest trying a different antenna – if you have a friend with AIS – try your 1299 on his boat. If your 1299 is indeed low sensitivity then a new AIS module would be the answer but you say it is old and the AIS units are not cheap so you may be better to just treat yourself to a new 1299A. You don’t say how old your 1299 is but the version3 is much slicker than the Mk2 1299 and the Mk1 1299 is – well its very old!
