If I have a Navionics Premium card in the left SD card slot and a blank SD card in the right slot and want to take a snap shot of a SI screen do I need to select the right slot or does the unit select it automatically? This would be in a 998.

I have and 1197 and keep the Navionics card in the right slot, and the blank card in the left slot (do not know if it makes a difference). When I take a snapshot it automatically chooses the blank card. I do not think it would try to record on your Navionics card. Also the Navionics card has a slide to protect it from recording on it, you may want to check your card.

It will automatically select the non-mapping SD card.

That is what I thought. Thanks for the reply.

I think the map cards are write protected anyway..and should not allow you to write snapshots or recordings..I do remember something a while back about partitioning the map card so that the map was protected from intursion yet allowed the 2nd partition to be read/write..
Dont know where that card map went..

On a 998C SI if both SD cards are blank it will record data to the right card slot.

96....... good info. Do you know if the right card fills will it automatically go to the left card. Also wonder if it splits overflow files between the cards on the 1st overflow..
Interesting stuff these sonar computers...
Thank you.....

I also keep my map/chart card in the right slot.
There is a selection on the Chart menu of Right Chart Card or Auto.
I thought that maybe the system would work faster if it didn't have to figure out what side the chart card is on, so I used to select the Right Chart Card setting.

But, it seems to always go back to the Auto setting. Probably after doing software updates.

I just leave the Chart menu setting to Auto now.

Good point ITG......in this case maybe auto is better...

Haven't gotten to that point yet but, soon we'll be mapping with SI snapshots so I may have your answer in the near future.

I had a 8G card in the left slot filled with readings and inserted a 4G higher speed card in the right slot. When I checked the 4g card at home after making two recordings all the info on the 8g card went onto the the 4g card. What happened

I had a 8G card in the left slot with recordings and a new 4G card in the right. After making two recordings on the 4G card and checking them at home all the info from the 8G card was also on the 4G card. What happened?

sonar2000 · « **Reply #11 on:** June 03, 2011, 06:01:12 PM »

Now that is strange. On the 1197 at 4.9 we had two cards in and it only wrote to one card. we never filled it up to see if it overflows.
Wonder now if 5.5 has something else to consider in recordings.
Where in the world are all these strange things coming from..
Wonder if it senses the card size and transfers.
I will get out this week and try the two card thingy and use different sizes.
We also have not gone beyond 2 gig cards either..
All work and no fun is starting to be a daily life..

Chuck looks like HB defaults to the right slot would be nice to know if it would switch to the left side if the right side is full
would be easy to check if you had two small cards all mine are 8 gig or more. Gary

sonar2000 · « **Reply #13 on:** June 03, 2011, 06:53:06 PM »

Gary, my thoughts also. I am going to try this weekend to take two small cards 256 or even 128 and try that sequence.
I cant find any reference in the manuals on who is on first and whats on second......

I will get back to this thread...
Others may try also and we can compare notes.

Man, this is great. I'm learning a lot more than I planned on when I asked my question.

Moose1am · « **Reply #15 on:** June 03, 2011, 08:50:33 PM »

In order to petition a card don't you have to format it first? And if you format the card you will lose the data on it. So I would not recommend doing a format on any $200 or $100 map cards. That would be an expensive mistake.

Most all SDHC cards have a physical switch built into them that you can turn on write protection or turn it off.

My 8g card was full and had already started to over write the recordings. but how all that information transfered to a 4G is confusing. The 4G was 20mbs while the 8G was 15mbs. I will be out today and tomorrow to see what happens.

sonar2000 · « **Reply #17 on:** June 04, 2011, 07:02:27 PM »

No we should not partition the card. I was only saying that in the past I had heard the manufacture did that but I dont think it is the case today.
Some of these nav cards are read only. But you dont want to override and lose you map.
I was just thinking how nice it would be if the partition was done today...at the time of manufacture.

I was not talking about map cards we are talking about taking your map card out putting 2 regular sd cards
in your unit start recording when first card gets full if unit will start using other card. Gary

sonar2000 · « **Reply #19 on:** June 05, 2011, 06:04:09 PM »

Gary, exactly right.....I think we may have two conversations going on here...
Also it rained here today so did not get out on the lake to try the recording overflow.
Will try this week..
