Team was helpful in selecting right dash cam for my car. Went with Thinkware U1000. Easy to install, but if you want to do a pro job yourself then take your time. Test the unit before full install. Use the instructions from Blackboxmycar website. Once you test fit, secure the front cam and start routing cables. I have an SUV, so if you want rear cam wires hidden, take time routing cable through rubber grommet at lift gate/body hinge. I routed using a zip tie, taped to rear cam power cable,then pulled it through. Very clean and professional. You’ll have to remove plastic shrouds but it’s worth it. Get the removal toolkit...it’s definitely worth it. Then full send rear cam cable up front, tucking cables away neatly. Another tip...get some tesa tape, it’s black fabric tape used to tape cable together. Looks pro and keeps wires together when routing from front cam to either fuse box, OBD port, or battery. Black box team helped me in choosing OBD as best power option as my fuse box is in engine bay and too difficult to get to. Using iRoad and works great! Thanks again Blackboxmy car! Jos
