A couple of issues here. For Helix updates you must have the update 2.280 on any G2, G3, G4 graph if the graph is < 2.280 when purchased, this is mandatory prior to updating the current update 2.800. When you update to 2.280 it deletes the basemap which you must update if you plan to use the new Lakemaster VX chips. The 2.280 update is on the website for each graph along with the basemap update for each graph. There is a basemap for the Helix 5-8 and a different basemap update for Helic 9-12. Make sure to encrypt your SD card prior to the update then download any of the updates to the card and it will know which update to apply to each graph. Be patient too. The update files are now much larger than in the past and it takes the graph a long time to recognize the new update 5- 8 minutes is common.

You can only hook the M360 to a G3 unit and it will only display SI from the M360. You will loose the ability to connect to the SI on the Transom. If you move the mega SI to the bow and move the mega DI to the consol you will only have DI and 2D on the consol except you can subscribe to the SI from the M360 on the bow.

A Solix cannot share a transducer with a Helix. Solix and Helix only share waypoints, nothing else.

waypoints are always saved on the head unit not the card. When you sell a unit make sure to download to a card and delete all waypoint to clear the unit for the next owner.

First thing I would try is to eliminate the ethernet switch by hooking the bow unit directly to the IPilot Link. If the problem goes away then it could be an ethernet cable or the ethernet switch. If problem persists then the head unit will need to be replaced on the IPilot Link. I have seen a couple of IPilot Link boards go bad in the head of the motor. If problem continues take it to an ASC to try a new head unit.

update your software

Waypoints are on Helix 7 not the card of any kind. They will be displayed on any card you choose as long as they are set to visible. No need to transfer waypoints to AutoChart card. I would transfer periodically to a blank SD card to maintain a copy of my waypoints in case of disaster.

If you shut off Mega and shut off Chirp on the Helix 10 you can share SI at 455/800 and can share 2D sonar. If you want to use the new Mega G2N Helix 10 with all of the new technology it brings to the table you will not be able to share sonar or imaging from Helix 10 to 998.

Follow the contour will only work on HD maps from Lakemaster. I the lake is not Lakemaster HD follow the contour will not work.

NOTE: Minn Kota motors with built-in Universal Sonar 2 (including those with i-Pilot Link) are not compatible with Humminbird’s Down Imaging Sonar. An external XTM 9 WIDE DI 20 T (83/200) or XTM 9 DI 25T (200/455) is required for all sonar readings with all HELIX 12 , HELIX 10, HELIX 9, 1100, 900, and 800 Humminbird Down Imaging units. An external XTM 9 DI 25T transducer would be required for the Down Imaging versions of the HELIX 7 and HELIX 5 along with the 788ci HD DI.

No. A DI unit cannot be used with a universal transducer even if the transducer setting is Dual beam or (83, 200). A DI unit can only be used on a trolling motor with an external transducer which is a DI transducer.

A 788 DI cannot be hooked up to a universal transducer. This is not supported by Humminbird and the erratic depths you are seeing is caused by using a DI unit which is transmitting to much power to the universal transducer. If you read the FAQ’s for Humminbird this is explained.
