It's really annoying this issue isn't mentioned anywhere except buried on the mods4cars website. I didn't discover it until after I finished installing it.

We recommend getting a ~6ft long power wire with 1 or 2 Amp. inline fuse, available in car accessory shops for example to hook up radar detectors or CB radios."
This was the case on older produced modules, current modules do not require this.
Please - if you have any questions, email me directly so this does not confuse other module owners.
