Use an old smartphone for bike navigation

 

I enjoy mountain biking off-road and often in areas with no cellular.  Sometimes I ride in areas with many established trails that cross each other and navigation would help.  I looked into bike navigation but they have small screens, are costly, and many of the features are redundant with my Garmin fenix 6x Pro Solar watch.  I also never trade in my old smartphones so I have several fairly recent ones laying around.  I decided to use my old Motorola Z4 smartphone as a biking navigation using.  First I needed a real robust mount.  I started on Amazon and found this one. 

It grabs all 4 corners and locks in place.  

I cleared and reset the phone, removing all unnecessary apps to minimize battery consumption.  I also put it in airplane mode, and keep WiFi and Bluetooth off to save power.  The Moto Z4 I am using also supports MotoMod batteries, of which I have a few.  I am using the 2200mAh unit primarily and I can hot swap in others if it gets low on the trail (which is unlikely).  I could also connect the phone to the USB port in the bike display to keep it charged if I wanted.  I removed the SIM card as well so it would not search for cellular even out of airplane mode.  Then I installed Google Maps, Trailforks, Garmin Explore, and GAIA maps.  All of these offer offline maps of bike trails.  There are many others too.  So far I found GAIA to be the best for bike navigation as it can ever store satellite maps offline. 

Here is how I organized the home screen.   

Here is what GAIA maps looks like.

Here is a video showing the use of this riding some trails.

This first ride was on a pretty easy trail.  I have yet to test it on harsher rides but so far it seems solid.  I am of course by no means the first person to do this.  I wanted to use an old phone, and not my current phone, just in case that mount breaks or I crash the bike.  Also, I didn't want to drain the battery on the phone I use normally since I want to be able to make calls, or message through my Garmin satellite messenger in case of trouble.  

2010 Mercedes E350 4matic - sold

 

I am selling my 2010 Mercedes E350 4matic sedan.  It has 167k miles on it but runs and drives great.  There is a slight whine in the drivetrain that has been there for years.  The rims have curb rash and some are somewhat bent but it does not cause any problem. It was hit in the back in 2019 but there was no structural damage and we had it repaired at Benishek & Will which is a very reputable body shop.  Current Kelly Blue Book value is $5,782 - $8,569.  I will sell it for $6,000 or best offer.  

I bought this car in 2015 from Autohaus in Peoria.  We took many road trips in this car, especially between 2015 through 2018 so many of these miles are highway miles.  The car has had very few miles since 2021.  It has always been kept in a garage.  This is the first year of the W212 body style and these have been great cars.
