Can't upload while connected to RX TX pins

I'm trying to create a RFID MP3 Player with a Nano. I've found several examples and can get the RFID portion working just fine. The problem is that the MP3 player module (the board is Serial MP3 player V1.3.2) uses the RX and TX pins for serial communication. If I have it connected I can't upload new sketches. From the research I've done it appears that having a wire connected to DO0 is the culprit. I get the avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 error. If I disconnect the MP3 module I can upload again. Is there a way to assign other pins in the sketch for serial communications or to just get around this error entirely while using the RX and TX pins?

Consider using SoftwareSerial on 2 GPIO pins of your choice for the MP3 player

Thank you. I will do that.
