​Apple Maps tunnel navigation can be dangerous

Bug can end navigation before you reach destination

Apple Maps isn't perfect for satnav at the best of times, but its treatment of tunnels is terrible.

Apple Maps isn't perfect for satnav at the best of times, but its treatment of tunnels is terrible.

While it won’t affect everyone, a serious bug reared its head at the weekend with me and the new iPhone 7. When you drive into a tunnel and then hit a traffic jam, Apple Maps keeps going at the same speed. While this is something I’ve actually wanted tunnel navigation to do for some time, you’d think that navigation would stop and wait for you until the next turn or tunnel exit.

I’m based in Sydney which has many tunnels beneath the city – many on motorways that lead out of town and which tend to be either fast or congested.

A bit further out is the M5 motorway and last weekend it was in a sorry state thanks to a breakdown half way through. This meant that on entering the tunnel at speed I quickly slowed to a crawl for many minutes while passing through the long tunnel.

Meanwhile Apple Maps had me going at the same speed. As I was approaching the obstruction Apple Maps had me exiting the tunnel and taking a right off the motorway and then a series of quick other turns.

I was still stuck in the tunnel but Apple said I'd exited and made two turns already.

Then it said I reached my destination and stopped showing the turn-by-turn route.

At that point all I was shown was an overhead view of my route which was very difficult to make out. Also, the screen would dim periodically you’d I'd have to tap it to wake it up.

Around this point I was passing the obstruction and traffic was speeding up. But even at slow speed I was having to spend more time than was safe scrutinizing the screen on where to go. On leaving the tunnel at speed this became very distracting.

When I did exit the tunnel, at speed I had to make out what was going on here with no place to easily pull over.

Not what you need from SatNav.

While it's something of an obscure, first-world problem, anything that causes confusion when you've two small kids in the car needs to be fixed. And many people who live around Metropolitan tunnels who own an iPhone could easily have bigger issues than me.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
