Question: To activate the GPS maps, do I need to contact a seller or the software developer?
Document: So far so good! I took it to the shop and they installed it with almost no problem. Everything seems to be working well. The CD player is great with the  only exception is it will skip a little if I hit a hard bump, and that is a big deal for some. But considering I bought it on a budget I'm satisfied! The GPS woks great after I figured out how to use it. I haven't had to feel I need to update the maps yet.
The map for mexico its incomplet. Only have a principal rutes. I need a map more actualize map incluied streets and avenues secundarys
They give you free maps update for the first year and then it's $70 afterwards, which is pretty reasonable. Unfortunately, they don't provide firmware updates to this unit, so if I encounter a glitch, I'll probably have to live with it, but none so far.
I disabled it because it got annoying.Aside from the music being cut off when navi voice is on. The unit is great. I give it a 9/10 because it has everything that i want in a stereo. I don't really need navigation but hey, $250 stereo and it comes with navigation. Can't beat that.
Maps that come with the unit appear to be fairly up to date in my area (Chicago).
Quality stereo. Has touchscreen and Bluetooth enabled and is very easy to use. Love the built in GPS. GPS is independent and does not require your phone or other device to work - goes through the stereo alone. Like that music will play with the GPs on screen. And this programs easy to my steering wheel controls. I suggest starting with 1st control on wheel and then the next in order. Then follow up with assigning stereo keys that match, Easier.
Good afternoon Mr Boss.You can install maps Bogota, Colombia?What is the procedure and costGracias por su ayuda
**EDIT:The GPS unit has since become non-functional after 2 weeks. We receive an error message every time now during navigation where the GPS completely FREEZES (some functions of the unit still are playing; like radio, bluetooth etc. After a minute or 2 there is an error message in Chinese/English that has the error message.I have contacted Boss who has been extremely informative, and says the unit is defective. I am currently working on getting a replacement through Amazon.
Movie playback is awesome. Has lots of extra features for managing DVD playback. The equalizer is powerful- be aware of changing it to proper setting before cranking up volume and setting the levels for GPS, Bluetooth and phone volumes first as well. The time zone and clock is a lil tricky, must change inside the clock and GPS for it to register right time change. I love this stereo. We bought 2. Also bought 2 TFT visor monitors.
Radio works great like all the features,,, GPS is very accurate  ...detachable face...I'm happy with it  ...also good price...will recommend to anybody
Answer: No its already activated
