hello jkkm newbie- i was a newbie 6mos ago when i got my first volvo, a 92 240 wagon. have repaired many of the issues with it with great help from sages on this forum . while not a sage yet, have learned a lot here. can help you with 2 items. for the repair manual , the best is the volvo 240 service manual by robert bentley. order it from autobarn.com . 2d, the best source for a radio is crutchfield.com. their price ,service and guidance is amazing. you probably have an oe volvo alpine am/fm cassette radio. crutchfield has a pioneer amfm cassette with more power and an installation kit for 136. email me if you want more detail(callpaladin@aol.com) or ask for oldduke on this forum. good luck oldduke.
