Hi,
Read datasheets if both devices are pure "request-response" type, so you may multiplex one UART interface to two "slaves".
*******
But I wonder what benefit a MAX485 could give with this problem. It just transfers data differentially, but still there's only one UART.

there is no need to send data to GPS.
Only halfway true. Many GPS modules support different interface protocols, including a query mode which sends data only on request. Looks like you didn't yet seriously check the options.GPS does sends data continuously without any request.
The datasheet.Can you suggest me a tutorial of how to configure UBRRL and UBRRH register for desired baud rate.
Ohh, ok..but still trying to figure out what is the issue behind garbage data. Can you suggest me a tutorial of how to configure UBRRL and UBRRH register for desired baud rate.
