question. I ran a Sidekick last yr on my 4920, used PF90363 cable to get it to the 2600. Worked great.
Got a new 4930 for this season and got 2 sidekicks. Now i know i can run them both, use another cable, BUT is comm port 2 for GPS only,,or will i be able to set up a 3rd product app on my display an keep track of both???  Manual say neh neh,, what do you say???
