My GPS is an original Garmin Zumo 450. I'm guessing it's 10+ yrs old now. I still run 2011 Trail maps (mostly because the 2016) ones I loaded into it don't display right for some reason. Never bothered me as I like to see the changes when I'm running off what was the old trail. This unit has probably been on my last 5 sleds and countless rentals. Not to mention, my boat, truck, car and motorcylce when I had one, (too dangerous an activity for me anymore...I gave it up). It is still on the original battery (charges and holds flawlessly) and I simply can NOT kill this thing. It works in -40 weather (touch screen and all). Not ONCE has this unit EVER failed me. It has pictures, music (not that I use that anymore as I bluetooth tunes into my helmet from my Iphone) for 3 years now. My core riding buddies know that "when the day comes" ....and it will.....that the "Zumo dies" it's going to be like a "holy sacrilege" moment for me. We WILL stop wherever it is (whatever the weather is) and have a "moment of silence" and "celebration of life moment". I kid you not on this.
To answer your question: When I first got this thing there was no such thing as a "glovebox" GPS. This unit was top of the line when I got it and the only realistic mount was a Ram and ball.
I got so used to and loved (and still do) the flexibility and mounting position options of a Ram mount that I doubt I could ever go back to something else. Yeah the new Garmins have way more features and Skidoo has implemented it into their overpriced GloveBox extension, but it's just not for me. I can move mine around to almost any place I want, at the height and distance I want with little to no problem. This year I raised the whole unit up WAY further than I have in recent years and I am very pleased with it. I run hard and fast most of the time (solo or with others I ride the same) and "glancing down" lower to see something (especially at my age) does not suit me well anymore. In fact the ONLY two things I ever glance at on my dash are "engine coolant temp" and "gas bars". I have found that my "eye" reaction time is much better, less delay if you will.
And now Skidoo's new attraction is this new dash and integrated app's. They can keep all that bulls#%t (and their price increase) and sell it to someone else.I know where i'm going and I checked the weather (always wrong anyhow) well before I left on the trip. And if I have ANY question as to "where i'm at" or "where I need to be" i'm CONFIDENT my trusty Zumo will guide and advise me. That's all I need (or ever want) at this point of my snowmobiling trips.
The original Garmin Zumo 450/550 series STILL sell for (relatively) big bucks on eBay. That is because they were arguably the BEST (and most rugged) GPS unit ever made. Hands down.
It WAS the BEST 375.00 (got a smoking deal on eBay) that I have EVER spent in my life. (well....that and my 22 yr old Kawasaki Mule)
I leave you with a pic I "dug up" from my 2007 Blizzard when the Zumo must have been new. Properties of pic say " March 9th 2008" I NEVER have a sled more than two seasons.My jackass buddy used to love to do this pose while we were doing trailside pit stops.
