Question: Does this item come with the SD card or does it have to be purchased separately?
Document: THIS IS A HUGE waste of money! Pay an extra $100 and get your money's worth! I bought this item and a month later the maps app didn't work anymore. The radio is just fine but the whole navigation doesn't work the manufacture is very hard to get a hold of and they won't give you warranty. The SD card is a bunch of crap! YOU GET WHAT YOU PAY FOR AND THIS IS THE WORST ITEM I HAVE EVER PURCHASED!
Went online and updated the micro SD card but that didn't help. (Naviextras.com) Also called PLANET AUDIO and after waiting on hold for 20 minutes they told me local points of interests show very little. If I had to do over I would choose a different radio.
This thing is loaded with adjustments. You can adjust the volume of everything individually in relation to each other, meaning that if you find your bluetooth music is loud compared to your FM radio music, you can turn down the relative volume of your bluetooth or turn up the relative volume of your FM radio to &#34;even out&#34; the volumes and limit having to adjust the master volume when you switch from one activity to another.
This means that your log only shows the calls you've made on this trip, and it only shows the phone number you dialed, not the name of the contact. The &#34;Received Calls&#34; log has never populated for me.-Navigation does not call out street names for upcoming turns. This is fairly minor, but having used a navigation unit with this feature, it is kind of nice to have the street name read aloud.
This is really annoying when you're at that crucial &#34;last few turns&#34; moment and your girlfriend calls you crying about her lip gloss or a kitten she saw online or whatever they think your life should halt for and you wind up missing your turn.
There are also several options for how routes are calculated, warnings for speed and traffic cameras, and even traffic (which I have yet to set up, so I don't know quite how it works yet). As I mentioned, 80 pages of User's Manual for the GPS, so there is way more to it than what I'm touching on here.All things considered, I'm very happy with this unit.
The user interface takes a very short time to get used to, and I find it very easy to utilize. Initially I didn't like how you input a destination, specifically that you have to input a city as one of the steps every time, until I discovered the &#34;History&#34; button that was right in front of my face the whole time, which saves the cities you've navigated to. Now setting a destination is a snap.-Volume knob.
The routes have been really good. In fact, it once sent me on a route that I wasn't familiar with which then became my preferred way to get to the next town to avoid rush hour traffic and stop lights. For this, I am forever grateful.-Navigation waypoints. It calls them &#34;Via Points&#34;, but you get the idea. You can set an ultimate destination, and then set other stops you'd like to navigate to along the way.
It looks good, it sounds good, and it works very well. If you've been looking for a GPS equipped radio that won't break the bank, this one is definitely worth a look. If I had a second vehicle, I would buy another of this radio for it.
In the event that you want to take a route other than the norm (to avoid a car crash, let's say), it seems that if the unit wants you to go a certain way, it'll try to get you to turn around even after you've passed the point where turning around would be faster than continuing the way you're going.
Answer: The radio comes with the SD card (microSD actually) with the map info installed. The map was a little dated (2012), and this radio does not come with free updates. I purchased a year of map updates for $69 - http://www.navizon.com/ if I remember correctly. The location for the map updates is on the NAV screen when it comes up each time. The NAV screen is a little slow the first time it is selected each day (~30 seconds) but after that it comes up immediately (switching between radio, bluetooth, NAV).
