Take it this time... Find if you use it or not, and if it is useful, or just another gadget that is nice to have..
A lot would depend on the trip. You don't provide any information about your trip - one day, multi day, on roads, cross country, so hard to say.
Anything with a battery can always die when you need it. Depending on how it chews batteries, multi days could need a ton of batteries to run it. Electronics typically don't mix well with water. Hard drops can also see them in trouble.
If its your only navigation and it stops working, you're up the creek. Also, the GPS will not contact anyone to call help if you need help, so, you need something else for that if that is what your thinking off.
Myself, cycling, I have paper maps, and a phone with a GPS that doesn't need reception to work, and offline maps. Only because I've always got my phone with me. Only used the phone a couple of times to check if it worked. It does, but I make more use of paper maps.
Planning the trip - know where help is, and know where the best bail out points are.
