Replacing SC-EM800 with EW-EN100

[donovan888]

Hello,

As I am using Garmin 1030 and I really don't need SC-EM800 display.

I have seen threads of upgrades but opposite what I am trying to do.

Except for junction it self, do I need any adapter or cable?

Is this correct junction box?

The sc-em800 connectors are sd300 while the ew-en100 uses sd50 connectors. So you cannot just swap them out without some changes.
Without knowing what bike you have and what else is on the bike the simple way would be to purchase two adapters sd300 to sd50 and two short sd50 to sd50 cables 150MM is the shortest available. As someone who did exactly the opposite I can see no real benefit to you of this change. Both the sc-em800 and the ew-en100 support both bluetooth and ANT + and hence would support your garmin without an issue. The adapters and cables are going to set you back almost £100.
There are two useful benefits of the display over the ew-en100. It provides odometer readings and it allows you to change between the 2 profiles from the display without needing etube app.
