Q: I use Google Maps on my Android phone, an LG K51. When I'm at home, and the phone is using Wi-Fi, I hear the app's voice directions. But once I'm in driving my car, the voice directions can't be heard. What's wrong?

A: There are several possible reasons that Google Maps' voice directions don't work in your car. Some are caused by phone settings and others are the result of phone-to-internet or phone-to-car connections. Here are some things to try:
• Check the signal strength of your phone's cellular connection when you're driving. A weak signal can keep the app from running properly.
• Make sure you are using both of the wireless connections needed for you to hear Google Maps directions through your car's speakers. The first is the basic Bluetooth connection to the car. The second is the "Play voice over Bluetooth" setting. Experts suggest that you go to Settings, click "Navigation settings" and turn on two features: "Play voice over Bluetooth" and "Play voice during phone calls."
• Your phone and car may have a bad Bluetooth connection. Turn off Bluetooth on both of them, then turn it back on. If that doesn't help, try deleting your car from your phone's Bluetooth settings, then starting the phone-to-car connection again.
• If the Google Maps cache memory is full, it can interfere with Bluetooth. To empty the cache, go to Settings, Click Apps and tap on Google Maps. Click "Force Stop" to turn off the app's operations. While still in the app, click "Storage," then click "Clear Cache." Restart the app.
Q: I have 40 documents stored as Apple Pages files; each contains embedded color photos and is two to three pages long. I'd like to consolidate the files and have about five copies printed. What software should I use and where can I get the copies printed?
