Actually, the GPS tracking is done via the internet and uses the same USB GPS antenna for your navigation. My carputer will connect to any open wifi access point it finds and update it location, or it will update via the inter via Bluetooth tether on mine or my wife's cellphone (Every time we get in the jeep our cell phones are usually in our pocket and automatically sync). The app I use for GPS tracking is free through my front end software centrafuse.
The OBD2 is a cable that costs around $70 and the software is another free plugin for centrafuse.
The web browsing is free as the carputer tethers via Bluetooth to our cell phones. You do however need a data plan with your cell carrier.
Climate control I am going to be using a whats called "The fusion brain", it costs about $50. You can also use mini steeper and sevo motors connected to your current controls. Its not expensive to do, but is very time consuming and requires lots of research.
Tire pressure. The kit for this costs $200, but is painless to have installed at any tire place. It then connects with the free app in centrafuse.
As for canbus, if you really want to use the on board amps, disk changer (Yes there is a way to control it via the carputer)or hear the warning chimes through the speakers, you just need a pac adapter. Costs $60 and works perfect in my rig.
A carpuer is much more capable then a mygig and will always have literally 1000x the options, but it is more complicated (And prob nmot as reliable, even though I have not had any issues yet) and not for the non geek at heart. It does cost the same (Can cost more depending how what hardware you get) if not less but will eat up a lot of your time setting i up.
In order to get gps info from the jeep while you're not in it as in being in another country, a gps system does not have the ability to send info to your phone or send a text etc by the gps antenna like my autopage security system does and my app on my phone will let me check temp inside jeep, check any info on the jeep ...start it, lock doors,,,,etc etc....which is a service called C-3 that you have to pay for because the unit that controls all this is what is called telematics...like a cell phone that you put a sim card in and it answers and calls with all this data just like a cell phone does....so you will have to buy that unit which will require you to have cell service that has a software to work with it to make 2 way communication possible. only other way it could work is you leave your cell in the car at all times when you are not in it.....Lo-Jack is only one way data....On-Star when it first started was not a gps system, it was telematics with a button for the driver to push and it calls the operator and they got info they needed from a live person and not til they started putting nav in it with a gps ant could that get turn by turn directions on the Screen......trust me, we are not at the tech stage yet to have a small moving sat ant to send info yet.....in fact for sat internet at home takes a bigger dish then tv sat to be able to send info back ...not talking huges internet...that's new...as in being affordable to have....satellite internet has been out for many many years, that's what remote ATM's etc have used and the equipment to get cable internet speed right now is several hundred dollars for equipment, and monthly bill starting at about $400.00...a month....the slowest....it's more reliable then comcast etc.....The OBD2 can be a dongle that plugs into it and then send info to a cell, which is about $25....so the dongle and the app work together......So web browsing will require me to turn my bluetooth on, pair it and then I have to start my Hot Spot or use my Tether on my phone each time i get in the car and it connects to the cell"s web which most new phones will have a problem with that running and it gets your text or a call or you trying to stream your music to your infotainment system all while it's also bluetoothing your calling side of the cell.....Not sure there is a phone that can handle being connected bluetooth to 3 tasks at the same time..........it can't.....a desk top has a problem trying that now....lol.....Canbus is alot more then you might not understand......most things that are changed in a networked (CanBus) which is what canbus means, the brain in car while have to be told of these unique changes all going on while is driving etc.....There is no way, and i mean, no one, unless you have a tool called the StarScan which cost about $5000.00 that will have to be done to a canbus car.....maybe that wouldn't a problem on a oldddd car......Cadilac Allante if you remember that a few long years back was the test/first vehicle to use a true canbus/network sytem.....so really i'm sorry, i'm trying to see how this is able to be a clean, warranty non voiding problem because the time setting it up each time i get in jeep and then trying to drive and with that many bluetooth pairing it has to do and we all know that nothing bluetooth connects to even one device 100% of the time and then it's gonna cause you to wreck and the new laws hitting the states later on will mean that if you are seen or caught with that cell phone playing with it to get it going while driving and the laws are, no text, no handheld calls, which means there will not be a cell in your hand if you are seen by cops etc etc......not trying to bust your bubble, but more thought into this, maybe? Google all these services etc I talked about and you'll see what i'm trying to get out...lol....Do you have specs on unit you're talking about, I'll invest time matching compatibilities with my specs I have to it's...thank you....ps..what hard drive is in it?....there aren't alot of choices of Automobile Hard Drives out there, maybe two, and they are between $250 to $500 for a 40 gig....a reg laptop drive etc will work, but depends on daily life, where you live, etc etc if that reg drive cann handle it....most auto drives are gonna be around 40 or so gigs and you will see online others selling gigs that are over 160 gigs, but they aren't made for what they are being sold for.....hey , that's what we do here in the USA...lol[/QUOTE]
If your cell phone is not in the car it uses the wifi antenna and as soon as it sees an open access point it will then connect to the internet and upload it's coordinates. Not a fail safe solution. If you cell phone is in the car it works perfect and gives real time tracking of your vehicle through your cell phones internet connectivity. However, if you ant to spend the extra money you can get a USB air card that you leave pluged into your carputer at all times, but this will cost you atleast $20 a month.
As for the computer itself, I use a mini netbook that can be found at walmart for $199 and I have it hiden behind the glove box. I did upgrade its hard drive to a SSD wich did run me an additional $80. It came with a dual core 1.8ghz Atom and 1.5 gig of ram. I purchased a smart power supply that uses ACPI over USB to bring the computer back out of standby once the ignition is turned on, it also send the hybernate command this way too. In the dash I use a 7" lilput touch screen that connects via USB and VGA to the netbook. These you can find on ebay or amazon for around $150. I also upgraded my audio to a USB Xf-I 5.1 24 bit sound card, that ran me another $50.As for the front end software (The software that makes it easy to navigate via the touchscreen and while driving) I use centrafuse, but there are many other front ends that are free (Ride Runner is a good free front end to use). Centrafuse also comes with 2010 navigation maps and works with most any USB GPS antena you can pick up for $20 on amazon or ebay. A very good resource to study up on carputers is mp3car.com, great site with a good forum.
As for bluetooth, its pretty reliable. I am using a Bluetooth Version 3.0+HS Class 2 device (30 foot range) with blue soleil and there has never been any issue using hands free, accessing the phone book and browsing the web all at the same time on the carputer. It auto syncs when in range of the carputer and it all happens automatically. I have a droid phone and that requires a smart phone plan with my provider, so I need internet/data plan no matter what. In other words its free for me to use internet in my jeeps.
One thing nice about having internet on the carputer is the streaming radio stations and watching youtube videos on the road.
If you have any other questions about the setup feel free to ask, I love to share.
