Help with connecting Adafruit Bluefruit LE UART to Arduino Nano?

Hi,
I'm not expert in Micro Controllers area, please help me to understand how to connect
"Adafruit Bluefruit LE UART Friend" to Arduino nano

According to Adafruit site, they are using pin :

(link for the BLE)

MOD to Pin 12
CTS to Pin 11
TXO to Pin 10
RXI to Pin 9
VIN to 5V
RTS to Pin 8
GND to GND

but pin 10, 11, 12 are busy, I'm using for SD card, and I'm using 3, 4 for GPS, what do you suggest?

SPI is a bus, usually four pins, of which three MOSI (11), MISO (12), SCLK (13) are common - you need to use a different pin for the chip select for the other device.
