Chinese SLI Emulator - enables you to have the area speed limit displayed on your dash if you don't have the option on your car.

Simple plug and play in the back of your 6WA / 6WB instrument cluster - 10 min installation and then easy to code via bimmerlink or ISTA etc (see the various forum posts on here in relation).

Reads the speed limit info off of your BMW sat nav maps (so note you do need this functionality for this to work).

I bought the one from aliexpress and it works fine but displays KMH, which as someone who has a bit of OCD found really distracting. If you're in mainland Europe or otherwise not phased by this will work fine once coded.

Can post photos etc if required (not much to show - is in good condition but appears as in other photos) and have the instruction leaflet.
