There's a load of information and opinion in this thread to re-read and digest, so pardon me if I restate what others have already covered. I do think
Michael's post (#82, above) is an excellent summary of the decision tree.
What follows is mostly a long (sorry about that) musing on my recent experiences and a short plan about where those musings have taken me.
My current collection of location / routing / navigation devices available for use when motorcycling comprises, in descending order of how much I use them:
- Google Maps app on my Android phone (99%+ of situations / usage)
- c. 2007 Garmin Nuvi 650 automobile GPS; internal battery no longer charges and I stopped updating the base map in 2015 (< 1% actual usage, but comforting to have along as an emergency backup)
- Garmin Edge 810 bicycle GPS, c. 2014 (used for moto purposes exactly once so far, yesterday)
Mostly the phone answers my needs.
- In nearly all situations it can tell me where I am, and how to get where I want to go, provided that I let it make the selection of routing.
- Coupled with that, the vast majority of my rides are in areas I know well enough that it would be hard to become seriously lost.
- If all else fails, I can bail out and follow / use larger roadways using the old-fashioned "read the signs, stupid" method of navigation, to limp home or wherever my destination is.
- Or stop and ask for directions. Please do not take away my Man Card for mentioning that as a possible approach.
- As a mostly fair weather rider, I'm not overly concerned about protecting the phone in wet conditions.
- If need be, I can stash it in my tank bag or other protected location and let the audio cues prompt me when I need to be turning.
- This relies on my having the bluetooth helmet speakers actually charged and turned on, but that's not the point here.
- Knowing that GPS and always-on display eats the phone's battery, I routinely keep the phone plugged into a charging outlet when navigating.
- Yes I've had issues in the past where something went wrong with charging and the phone eventually quit.
- I've yet to fail to reach any destination because I could not use my phone to navigate me there.
- Yes it may eat data
- So? I'm already spending discretionary money simply by choosing to own, register, insure, and operate a vehicle that serves no practical purpose, and which is therefore clearly "for entertainment purposes only" as the saying has it.
- If I already have the base map saved (next point) it doesn't even have to eat my data plan unless I want / need live traffic info or imagery views.
- Reliable navigation needs a base map and cellular coverage, doesn't it?
- Base map, yes. Cellular coverage, not so much.
- Since Google enables me to download and save their maps for a period of time, a bit of foresight lets me do that while still connected to a WiFi network.
- Downloading and saving the map also eliminates the problem of how to navigate through areas with no cellular data coverage, provided that I calculated the route while still in a covered area.
- The GPS feature works even when I'm not connected to the internet, as when I've traveled outside the U.S. with no SIMM card for the non-US network. All I need to do is download and save the necessary map data ahead of time.
HOWEVER, in a few ways the phone is lacking.
- Google Drive lets me upload and display a GPX file as if it were a route to be followed.
- The Google Maps app will display that route on their base map, right up until I switch from map viewing to navigating or routing.
- As soon as I start searching for a destination, or when I hit "Start Driving" without selecting a destination and calculating a route, my GPX data disappear. They stay gone unless and until I discontinue navigating.
- Without being in Navigate mode (or "follow me as I drive" mode), Google Maps does not keep my position centered in the map view and move the map window as I travel. That make is impractical to leave the GPX route displayed and simply push the "re-center on my current location" bulls-eye every few minutes. (Not compatible with the moto gloves I wear.)
SO- if I want to pre-define some long sequence of routing- a tag run or multi-day cross-country ride, for example, where I want to control the route and make several stops and also want to choose the small lanes and byways that I prefer, and not the "fastest' or "shortest" options Google wants me to use, I'm SOL when trying to use the phone.
That brings me to my Nuvi. It's old and showing its age but still seems to know where it is most of the time. And on the few occasions where my phone has come up short, it's been a comforting fallback option.
At 12 years and counting, it certainly no longer "owes me anything", and isn't my primary navigation tool any longer. But, I must have at least a trace of Scottish blood as I hate throwing something away if it still works as intended. That said, the Nuvi is clearly near the end of its useful life. I have decided it isn't worth paying Garmin hundreds of dollars every few years to get new maps for a device whose internal battery no longer holds a charge, and which is outdated in terms of the features it offers.
Specific capabilities / amenities it lacks, apart from only functioning when on external life support, include lack of a Bluetooth interface, and an inability to ingest, display, and navigate predefined routes from GPX files.
- I can live without the Bluetooth interface.
- The inability to load predefined routes, on the other hand, is becoming more of an issue, particularly in light of the phone's inability to support that function.
- So, the Nuvi may be on its way to the back of a seldom-opened drawer somewhere.
The Edge CAN ingest, display, and follow predefined routes. YAY! And, it's pretty weather resistant. BUT:
- It's got a very small display area, as the expected use on a bicycle has my face much closer to it than it is on a motorcycle
- I've not found or contrived a good way to mount it, yet, though I also haven't put much effort into that problem.
- It's not clear whether I can keep it charged while in operation.
- As a bicycle device, the Garmin engineers may have rightly presumed that it would not have access to a charger while in use so it would not need to support simultaneous use and charging.
- When plugged in to the wall wart, the display switches to a "Charging" mode
- Its battery, like the Nuvi's, is beginning to show signs of having been discharged and recharged too many times. It still runs for a few hours but I don't think it's as long as it used to be.
- Given that a moto ride can easily last 12 or more hours, battery life limits are an issue.
- I discovered yesterday that it fits nicely in the "cell phone" pocket at the end of the left sleeve on my cool-weather riding jacket. That pocket features a clear plastic panel that lets me see the display of whatever device it contains.
- I was able to read the Edge almost as if it were a wristwatch, with a short glance.
- But even short glances take my eyes off the road, and are therefore hazardous.
- While the same is true of my phone and the Nuvi, they are positioned so that it takes just a flick of an eye to catch a peek. The Edge, on my sleeve and with its smaller display, takes a longer change of focus. And the plastic cover of the pocket can add to the difficulty of focusing on / seeing the display.
- It's very close to the time of year where I switch from the jacket that has the sleeve pocket, to my mesh jacket which does not have such a feature.
So, what to do?
- I am not going to splash out several hundred dollars (or a thousand) for a Zumo. Simply not an adequate return on the investment, for my needs.
- Short-term:
- Stay with the cell phone, backed up with the Nuvi. When planning extended travel, take the precaution of downloading maps for the areas I'll be in so they are available if/when I am offline.
- If going on a multi-day road trip that follows a preordained route, print the route as a cue sheet and navigate out of the tank bag (it has a big clear panel on top, obviously intended for displaying and reading a map or directions listing).
- Look into contriving some sort of home-brew RAM ball and PVC tubing mount for the Edge; look into whether the Edge can be fed power while operating.
- Intermediate/longer term:
- Replace the Nuvi with a newer, budget-friendly automotive GPS that supports loading, displaying, and navigating externally-defined routes. When traveling, or when it "matters", use the new device as my primary navigator instead of using the phone.
- Support for alternate base maps, such as those from Open Street Map, is a plus but not a must-have.
- Ditch the Edge for moto use
Sorry for the long post; it's been a useful way for me to analyze the issues and organize my thoughts. If it helps anyone else out, great. If not, that's 15 minutes of your life you can't get back. Sorry.
