All right, thanks for the fast reply! I didn't figure it would really cause any issues, since it's really just being used as a signal wire and not the main power for the hardwire boxes, but I figured it couldn't hurt to ask. I'll check the wiring diagram to make sure they didn't change the functionality of that specific fuse. I'm just going to ground them in the same place. The Garmin hardwire box has a 10' cable, which I believe is enough to even reach the back, so the boxes will both be up front. Just in case, I bought a microUSB extension cable so that it'll reach for sure.

It's such a shame that none of the reasonably priced dual dash cams are made well enough. I was really hoping that the Cobra dashcam would work, since it comes with a rear camera that's connected by a cable, but the reviews aren't good.

 

For what it's worth, I have a ThinkWare F800 with rear view camera sitting in the garage I'd be open to selling:

I got it for my spouse's car. But now that I've tried out the WayLens Secure 360 on my own car, I've ordered one for her car, which leaves the really quite nice F800 without a home. PM me if you're interested. (I honestly don't remember what I paid, but I can check, and then cut that figure to something reasonable.)

The F800 is a better choice if being rear-ended is your worry; the Secure 360 is more oriented to vandalism and parking lot incidents than documenting road rage and tailgaters.

PM me if interested.

 

I'm actually kinda partial to the Garmin line, and since I already have the 45, that one will go on the back glass (it's 1080p) and I'm gonna go with the 55 for the front, since it does 1440p (and since I've already ordered the second hardwire box). Thanks for the offer, though!

 

Just used this write up last night before super to get power to my radar detector. Had everything ran just wasn't sure which tap to use for the fuse box.Thanks!

 

I just want to thank you for this write up. I would have never thought about the fact that the lighter outlet would momentarily switch off at ignition.

 

I want to thank you for this!
I am in a situation now where someone keeps denting teh side of my car when I park at my GF's Condo. I will install a dash cam and hopefully get him or her on the act!

Thank you!

 

Thank you very much for putting this info together!!!

Cheers

 

Thanks a lot for this great tuto.

Hello, I am about to install a tow bar on my F56 Cooper non S in order to mount a bike rack. I need 12V in the boot to install the relay module.
I don't have the 12V socket in the boot.

Could someone explain what would be the best to route a 12V wire in the trunk ? (my F56 does not come with Socket in the trunkà
Can I route it under the door sill trim ? After the sill trim how can I go to the back of the car? thanks

 

Thanks, installed my blackvue dashcam today and used fuse 52 for switched power and 42 for constant power. using a power magic pro so it should auto cut off at my set voltage setting.
