Manage Favourites/Home/Office locations on Garmin Nuvi 40LM

Garmin Nuvi GPS allows the saving of favourite locations into memory so that there is no need to re-key in the same set of addresses over and over again if you need to go to such places frequently. For example you could save Home and Office locations into the GPS and you could quickly activate it to navigate to those locations from wherever you are on the road.

There was one day which I accidentally saved a wrong address as my Home location and I had a hard time figuring out how to change it on my Garmin Nuvi 40LM. I used to be able to able to do it easily on the Nuvi 2465, which often had menu options within the navigation screen. This is not the case for the Garmin Nuvi 40LM.

I managed to find out how to do that one day. As below are the steps required.

Start from the home screen. Tap on Where To?
Tap on Favourites. (You may need to scroll up or down the menu to locate that option)
Tap on Home (or any other favourite locations that you want to remove)

Note: I do not live in Teban Gardens, this is just a bogus address.

A map of the selected location will be presented. Tap on the white speech balloon that is surrounding the address field.
You will be presented with some options that you can use for that location. Tap on Delete.
Confirm the deletion by tapping on Yes.

That location should then be gone from Favourites.

Unstable Wireless Connectivity

A few weeks ago I have started to experience unstable wireless connectivity within my home network, which is connected to the SingTel Fibre 100Mbps.

First of all just to give a brief overview of my home network:

I am using the ASUS RT N56U as the main wireless router to connect to the Optical Network Terminal (ONT) in the living room. To extend the wireless coverage in my study room, I deployed the ASUS RT N15U running on Wireless Repeater mode (The N15U also has the Router mode as well as the Access Point mode). 2 PCs are connected to N15U's gigabit ethernet ports, the printer is connected to the USB port and my other work laptop is connected to the wireless network extended by the N15U.

Initially I was thinking that the ASUS router and repeater must have been acting up to give me weird connectivity issues (the 2 PCs and the laptop start to have intermittent Internet connectivity at around the same time in the evenings). Could it be due to the extra load in the evening caused by the 2 PCs, 1 laptop, various mobile phones and tablets that are connected to the home network, thus causing the strain to the equipment?

I even bought the Linksys E2500 as the replacement for the main router.. but the problem persisted.

...until I read that such wireless connectivity issue could be related to the fact that more and more wireless base stations/routers are springing up among my neighbours - This could cause interference to the wireless signal and effectively lower the connection speed or even cause disruptions.

Immediately I tried changing the N56U's control channel (to a channel that is less used - 13. I found that out by performing a wireless network scan via the N15U) and narrowing the channel bandwidth from 20/40MHz to only 20MHz. Voila! the wireless network speed improved tremendously and the network bandwidth test (for my laptop) at speedtest.net yielded up to 20Mbps upload speed, which I am quite happy with (considering that the laptop is at the other end of the apartment away from the main router and is also connected via wireless).

Now I have to scratch my head to think of what to do with the Linksys E2500 router.

Garmin Nuvi 40LM

Recently I have upgraded to the Garmin Nuvi 40LM for my GPS needs. "LM" stands for lifetime map updates, so I should not have to worry about having to pay to update the maps from now onwards.

There are free maps out there that could be downloaded onto the device, but in my opinion they are not as useful as the official Garmin maps.

The Compass and Bluetooth functions (can answer phone with the GPS unit once they are paired up) on my previous Garmin Nuvi 2465 were not very often used. As for the voice command, it was only accurate when dictating numbers and not words (maybe it was my diction that was causing the problem) but anyway it did not prove to be useful under most circumstances.
