The antenna cable is just regular smb cables. Search on eBay for smb female to smb female cables. You should be able to buy a 15 cm one for about 4 to 5 bucks. I bought the angled plugs one for 4.20. Straight or angled ones is your own preference.
Running the mic wire to glovebox will mean having to remove the door sill trims and globe box. The door sill trims are not easy to remove and put back and you risk breaking something. Since I had no existing mic wiring, I ran mine up the C pillar, over the roof, removed the A pillar trim to tuck the wire under the airbag and then to the mic location. I used about 5 meters of cable for this. Assuming that there's no difference with existing voice control and voice control after Bluetooth activation, this wiring may be easier and faster since only the A pillar trim needs to be removed and this is easily replaced as well. Of cos it will be best for you to test if this direct connection for the mic will work first before running the mic wire.
