"Horrible Signal if you live in Capital City with big building, trees, and big houses!"1.5 starson by jlingo527
Pros: Multi Routing, Where Am I, Where do I Park,
Cons: POOR Signal in certain cities.
Summary: I love Garmin, I have used 300 and 400 series before I decided to go and buy Nuvi 750. I thought it was pretty cool to get rid of those flip up antenna. I was also interested with the better software features such as "multiple routing(Plan Ahead) and Where am I?" I used this GPS in few countries and few cities by now.
I would say Nuvi 750 HAS GOT THE WORST SIGNAL RECEIVER out of all other Garmin models I have tried. Don't get me wrong. When I was in California and Nevada for a few weeks, I thought the signal Nuvi 750 was marvelous. I was able to lock into the satellite fairly quickly within minutes. But the minute I drove to downtown LA, I started to experience signal problem.
I also felt the problem was growing when I was driving in Montreal Canada. It took almost 15minutes to lock into the satellite in the car. But The worst was when I took this Nuvi 750 to Jakarta, Indonesia which considered to be a very crowded, polluted, and heavy traffic with high building city. I WAS IN MADNESS. In LA, it took me only a few minutes to lock into the satellite, but in Jakarta especially when I was inside a moving car, I couldn't lock in at all, even after ½ hour of placing Nuvi 750 on the dashboard. Once, I got the signal locked in, I still experienced a lot of "loss satellite reception" problem.
I didn't experience this problem with previous Nuvi models with flipped up antenna.
The Good News is: The problem could be rectified COMPLETELY by buying GA25 MCX Garmin external antenna. It's such an exceptional antenna for the price. Now, I could even get signal with Nuvi 750 in the building, Jakarta, Indonesia.
Honestly, if you live in the city, it's very hard for me to recommend Nuvi 750. Better get 600 series. I'm not sure if 800 series has the same problem. Signal is a very IMPORTANT part of GPS. Without signal, no matter how good the features your GPS have, you won't be able to use it at all.
