2005 Humminbird Matrix97 won't read Navonics MMC fully.Anyone had simular trouble.

[Magneto]

Placed MMC into another sounder and all the detail is there, back into the matrix with a factory reset and set to show "ALL" and a reef hazard is just surrounded by dots no +++++++++++++++++ to indicate a real hazard. My neighbor who is familiar with the bird checked all the setting and confirmed them correct.
I wondered if anyone else has had this trouble and were they able to correct it.
Humminbird didn't say to much.
I cleaned the contacts on the navonics card sprayed contact cleaner inside the slot, no change. A curly one I know but maybe someone out there has had it happen too.
Thanks in advance for any help..

Just spoke to Maritime Electronic Services Fremantle, who have helped me out before. Greg said it's a fault with the unit itself and that the Bird's are not a good choice when I suggested Furuno as a replacement he said it is to hard to drive and suggested waiting for the new touch screen Raymarine at the end of the year for about $2200. A lot of coin, but we'll see how things are then.
I know there are others out there that will bitch about what I have quoted but these guys have 35 years of actual experience with electronics that float. I add this because I often see the question about sounders/gps brands and you can't beat a good sounder for finding the fish. Regards to all who read this. Subject closed

Hi all, I thought my chartplotter (2004/2005) had seen better days until I realized that after registering at their site, a bit late I know, it gave me access to the very lastest Matrix 97 update d/load, with the the unit not reading all of the detail in my Navionics Gold card I decided I had nothing to lose and go with the current update using the MMC/SD slot and it worked. Now seeing all the card detail and it added a new heading to part of the menu and changed something with the sounder too and gave more adjustment to the scroll speed. After setting the unit back to "Defaults setting" as instructed then powering down , powered up with the SD/update in the slot for successful update. It's like new again.
P/S Backup your Way-points first as I did lose mine but no problem as they where in HumminPC program, D/load to SD card and and into MMC/SD slot power-up and there they are back again. The main Humminbird D/load went straight from the desktop into the SD card to the 97 unit, no prob.
I hope this might help anyone thinking of doing the same.
Cheers again
Highly recommended......
