- In step 2 (see figure above) you could connect the “Galaxy S5 NEO” from the Head Unit (HU) 

side (other phone would be disconnected), but you cannot connect “Galaxy S5 NEO” from the 

phone side! 
- HU connects the phones as ordered in the list (if no Driver Profile with personal phone 

activated) – if Bluetooth is activated on phones. 
- Turning off Bluetooth on the phone and on again does not auto connect Bluetooth (in most 

phones)  

• 

Bluetooth must be connected manually on phone or HU 

•  Some phones may not connect Hands Free (HF) and media  
• 

Full ignition cycle is required in this situation

Critical points:

- If there are multiple HUs on phone list it can CAUSE problems with connection and phonebook 
- Every time you connect your phone you are asked for confirmation of phonebook (phone does     

  not remember) 

•  Add Work/Home Address
