The TPMS tool is of no use for the SD's. Maybe you can sell it to someone. The TPMS is probably not related to the radio issue. There have been cases of the TPMS acting strangely due to cellphone chargers or some other device that might have a harmonic of the TPMS frequency. Try removing any chargers that use 12v and go get a cheap 120vac charger from wal mart for like $8.00.
The radio issue is strange for sure. Are you saying the radio does not turn on or it is on but no sound? By change have you tried disconnecting the battery cable for a few minutes?
