OTR1000

A photogragh of your connector would help, is it this:-

I would call this (90 degree) micro B male, it is very common on android cell phones

 

I'm not quite sure what you are trying to archive, are you trying to make a cable you already have longer or make a cable you don't have ?, is it the right hand connector that plugs into the OTR1000 ?, the right hand connector looks very like the picture in post #2, but my picture has 5 connectors, does yours have 6 connectors ?

I am not sure what your left hand picture is of, but it seems to have 10 connectors

 

I have only just realised that your photo shows the ends of two different cables, the 10 way 'special ' connector on the left connects to the magnetic mount and supplies power from a 12 Volt car adapter

The connector on the right is a standard micro USB connector and supplies 5 Volts directly to the Dezl OTR 1000 unit (NOT THE MAGNETIC MOUNT) from a 5 Volt USB connector, if you want to use USB you can power the unit directly from this standard connector (see the link at the end of this post)

If you must use the 10 way 'special ' connector to the magnetic mount I would make sure that Aliexpress are selling the connector that you require, the cheapest alternative seems to be this Garmin item :-

This unit may have a 12Volt to 5Volt converter in it with only 2 wires going to the 10 way connector, you would need to check that the 2 wires are supplying 5 Volts and then connect a standard USB cable to these 2 wires

However is is possible that the magnetic mount requires a higher input voltage which would explain the non standard connector, in this case you won't be able to use a USB cable to supply power to the magnetic mount

I have some extra notes on the 10 way connector in this link Click Here
