Hi

Any suggestions on how to hardwire a dash cam on Mercedes eqv? Has anybody successfully installed one? Thanks.

Update. I was looking to install a dash cam to my EQV but was not happy with the specs of the Merc cam that could be hardwired/installed by the rep. I opted for a blackvue that has far more features but connecting it to the 12V port means that there is no parking recording when the ignition is off. Hardwiring the camera correctly should have been straight forward but there is very little info available for EQVs. I purchased an OBD cable for the blackvue (connects to the OBD port under the steering wheel) and the camera works fine (with parking mode on). Problem solved.

Well done. I think some dashcam models have their own in-built battery and/or settings for changing 12v battery drain cutoff point and I think Blackvue would be like this. I know little about wiring but EQV manual suggests you should have got a separate "Fuse allocation chart" supplement, for if you were wiring directly to the fuse box else the rep should be able get this information. Wiring to 12v socket might also work with a dashcam in-built battery to prevent power cutoff

Yes they do, Blackvue has something similar but these are for ICE engines so the dash cam will not drain the battery if the alternator is of (engine off). The EQV should not need this because in theory the 12V battery is charged by the main battery (should run the dash cam for a few years non stop!). There is a fuse box on the passengers feet area but you need to find out which fuse is live when the ignition is off and the hardwire the dash cam (piggy back fuse) and attach grounding to bare metal. I was planning to do this but the OBD cable works. Dachcam batteries again are useful for ICE cars and they will be drained if the car is parked for a long period of time. The Blackvue battery system is also fused but I have the latest model (900 Xseries) which has internal fuse for protection so this is not necessary. Be careful if you buy the OBD cable X series this may not suitable for older models (for the above reason) therefore you need a different OBD connection.
