"No Service" on car display when connected via BT

Last week a bought Samsung note 9. When I connect my phone to my car's stereo/head unit display (C-Class 2013) via bluetooth the signal display for cell service displays "No Service" Sometimes it will show a signal for a few seconds when first connected and then will change and show "No Service".

The phone works normal and even i can makes calls. But no service bar shown in my car desplay. I need to restart my phone every time a get in the vehicle so the service bar can show up. Please what is the problem.

Is your car's software up to date? Have you recently updated your phone?

@userkkS8hfPhaj: Do you have file sharing enabled?

Where can I find this file sharing option?

In the Bluetooth settings all are already enabled (call audio, media audio, contact and messages ).

I don't find in the Bluetooth settings an option called  (file sharing ) ?

Give this a try:

  1. Settings
  2. Apps
  3. 3 Vertical Dots
  4. Show System Apps
  5. Bluetooth Test
  6. Storage
  7. Clear Cache
  8. Clear Data
  9. Restart Device

Unfortunately it didn't work.. Still the same problem (no service). I have to restart the phone then it works fine till the Bluetooth connection disconnected . Every time I need to connect the phone I need to restart the phone . Iam facing this problem just with the note 9 !

I will be very grateful for solution.

When it states ''no service'' on the display of your car, is not connected or is it connected and just displaying the message?

It is connected  and even i can make calls from my car. It just displaying all the time "no service".  Its like the phone won't share the service information with the car unless I restart it !
