Some time ago I purchased the CP-Flight MCP and EFIS.
Now I purchased the NAV panel.
I have linked the NAV panel from the EFIS panel (captains side) with the enclosed 2 meter 5 pole DIN cable.

But the cable is too short for me so I have a question:
My question is:
1) can I use a standard 5 pole DIN cable from a shop or do I need to buy a special one?
2) can I use a length of 3 meters? (2 meters length is delivered with the product)
