Hello Ted

How are you doing? You have a Sirius XM, right? I'll be standing by for your response.

Thank you

Relly

Ok, you have the sirius xm satellite radio? Will it receive a signal when you restart the vehicle or do you have to refresh the system manually to have  a signal?

Ok Ted, can you access the vehicle? 

Great... I will have to ask you to remove the negative battery connector and let it sit for 5 minutes or more before reconnecting it. This will reset the radio's system and can get it back to it's normal operating state. You will need to get a refresh signal again and then try turning off the vehicle. To test, start the vehicle and check if the radio is good. I'll be standing by for the result. Goodluck Ted!

I see, is this a factory installed radio Ted?

Ok Ted, I will have to ask you to take it to the dealership. Two things I suspect, it's either there's a faulty chipset in the radio that needs to be fixed to retain the memory when the car is off (can be loosing current/voltage supply to the radio) or it may need a software upgrade to resolve the issue. Is there anything else I can add or help you with Ted?
