How do you program the radio in a Volvo s60?

My 2004 volvo s60 67000 miles. need help by volvo techs or volvo gurus?

• with just about 67000 miles on it has had some wierd things going on i have a weird thing happen and its only in hot weather, i live in a 4 seasons state and 3 out of the 4 the car runs great. but in summer i get some weird driving issues. the car will sometimes lerch forward unexpectedly or the brakes are grabbing the calipers , and says a severe break failure has happened, sometimes it might loose power and other times it wont, the radio will still work, but nothing else will locks, mirrors, windows, gauges all drop, time and temp go blank, as well as the trip. ill pull over to the side of the road turn the car off and than turn the car back on i will have a srs airbag service urgent on my dash sometimes it will happen again right away and other times it wont happen for another couple of days. i also had the car taken in last summer and the dealer said there was a fault happening somewhere near the engine and put a b block and checked the electrical connections. but a year later im having the same problem. i have been reading around and it sounds like it is a ecu problem (is that the same as the ecm). i also will refer to this question because i get the same error codes but i wanted to give a more accurate description. i could use an answer pretty quickly. http://answers.yahoo.com/question/index?qid=20100420124543AAmOBm6

• Answer:

  This vehicle has a lot of modules, and they are all networked together, so if one has a problem it can have an effect on others. This means it can be very difficult to diagnose these issues. To start a Volvo tech should pull the diagnostic fault code info from every computer on the vehicle, record the data, then erase all the fault code info. Drive the car and recheck the fault codes and see if any reappear. All the software in the modules should be updated too. You may have a bad module or an issue with the network wiring, but only a well skilled Volvo tech is going to be able to find this problem.
