Xplore with ultrex questions.

I recently had a full electronics upgrade done on the boat. 2x Xplore 10's with a new ultrex and have a few questions and would appreciate if anyone here could lend a hand. Im coming from some lowrance HDS units and a terrova trolling motor. I have done all of the updates except the current, didnt notice the update until i was out the door to go fishing this morning. I do have the one boat app on my phone and used it most of the day today, works pretty cool.

1st - I am a slow troller for crappies so I recorded my 1st route this morning from the phone app. After recording I can see the route saved to the xplore under iTracks but how do I get to "replay" the track, for lack of a better term? On my old terrova there use to be a setting, on the remote, to start route and then select which way you wanted to go on the route i.e. start from the end or start from the beginning. I do not know what this setting is on these units.

2nd - I tried to setup the transducer today to use the trolling motor transducer. I got in to the transducer settings on the xplore but was fairly confused by the settings. Everything is networked together through a hub, but I couldnt figure out how to select the actual trolling motor. It looked like everything was set to auto configure and for some reason it kept saying "this unit" for the transducer. When i did get in, what i thought was correctly, it had quite a few different transducers to select. A quick trip to Johnsons website said to select the "Chirp" setting which I did, but again, I wasnt sure if that was right or if it was the actual transducer on the trolling motor. I mean it must have been because i was getting sonar, right? The trolling motor has a mega down-imaging on it, which i could switch to down imaging and it worked but im not sure how or what selection to use.

3rd - On the trolling motor foot pedal. Its been years since I actually used a foot pedal and im not really sure if im sold on the pedal yet, its big and gets in the way. I controlled the boat most of the day by my phone, instead of using the small tiny remote they included as I might try that little remote out in a day or so. But that pedal, damn man, when i did use it today i was all over the place, the thing is so quick when you want to turn and i mean like really quick. I was zig zagging all over the place and no, i didnt want to zig zag today lol. So if there any sensitivity settings at all for that pedal? Im actually giving some thought on contacting my boat dealer and going back to an ultrex, depending on how the remote works out but the pedal really just gets in the way.

Thanks all for taking the time to read and help out. Its appreciated.
