Icom IC-M505 DSC \"Position Report\" Problem

I have a IC-M505 and it appears correctly to receive GPS data, and displays date, time, lat, long, speed etc when the [channel+enter] button is pressed. But it wants manual input of position and time before it can send a position report??

The display does not show and “???” symbols to suggest that the NMEA data has any errors, and the NMEA sentence is RMC being output several times a second on NMEA to the radio

The problem with Position Report Call

Press menu to enter the DSC menu. This works correctly
Rotate [channel] to select “Position Report. This works correctly
Rotate [channel] to select the pre-programmed individual address. This works correctly and select an address

Since the IC-M505 has a valid NMEA position input, the radio should display “Position report ready”. However, it displays a screen to enter the current position and time. This screen is pre-populated with the GPS position and time data and I have to [channel+enter] on every character to be able to move to the “Position report ready” screen. It is then possible to transmit the position report. I am sure that I have used this before and have not been prompted for manual position input!

The manual clearly states in several places, that there’s no need to enter position data manually if the position is available from GPS. The menu item under the DSC menu to enter position is not shown, but every time I try a position report, it wants confirmation of the position. I tried turning the radio, GPS, plotter etc off and on, but this makes no difference. Also makes no difference what station is set as the recipient of the position report call.

Has anyone else encountered this problem? I wouldn't want to be in a position to have to input position manually if I were in the unfortunate position to have to press the red button.

I've written to Icom re this, but it anyone else has a '505 and can check this and PM me, I'd be grateful.

Thanks

My handbook specifically says that if GPS NMEA 0183 version 2.0 or 3.01 is connected, then the manual input screens don't appear. Is it possible that your GPS out-put is say v. 1.5 ? It may be worth checking, otherwise you seem to have a fault. Icom tech support by e-mail is very helpful.

I was about to post a very similar problem myself, so excuse hijacking, but the relevant bods might be able to answer both at once,
my silva radio wont show the position though it is NMEA conected to the Cobra chartplotter, I also tried it with a Garmin GOPS, still no position showing
 
Cobra settings...

Have you ensured that the Cobra plotter has been set up to output the data properly? (Might need to check the Com Settings in the System page).

As of 3rd December, this problem is still under investigation by ICOM Japan.

I wonder how long we'll have to wait for ICOM to issue a fix. The warranty period clock's tickiing...
