LockPick GMX560

Waste of Money

I paid over 300.00 dollars for this thing and it worked for about two months. It does not work anymore and I have reported it to the manufacturer with no reply. The LOCKPICK blinks on an off and doesn't work like advertised. Completely wasted my money...

Escalade Lockpick system usage

I highly recommend this Lockpick for the escalade. I own a platinum ESV model and this is a cool feature to have specially with YouTube videos and Pandora playing on the front screen. The only thing that would be nice is that if it would remember the mode instead of punching the mute button every time the car gets turned off.

GMX-550 Work Great!

The GMX-550 does exactly what is advertised. My specific reason was the iPod interface and ability for a front camera. I installed the GMX-550 in my 2010 GMC Sierra and had to place it under the center console, forward of the utility tray and not under the radio as advertised. There is absolutely NO room for the wires and unit under the radio. It is very important to remember that when activate the NAV In-Motion option, your GPS does not work for a little over a minute. It appears that the vehicle speed is disabled or ‘zeroed’ in order for the NAV In-Motion to work while tricking the vehicle that it is stopped. I’ve had problems with the GPS catching up after exiting this function.

Adding a front camera allows very close parking and prevents bumper collisions. I installed a High Resolution 170 degree back-up camera from eBay ($18) under the grill.

Add a blue tooth interface to securely unlock doors, window, and other features associated with the vehicle control bus/protocols.

Pros: * VERY easy to connect matching wiring harnesses and plugs.
* Intuitive interface
* Reliable performance
* iPod, iPhone, iPad controls ported to the vehicle’s touch screen
* 6 feet of iPhone, iPad, iEtc, cable to reach front and back seats
Firmware upgrades
* Multiple video management configurations. Dual back
monitors, Front monitor, Video game input, Camera
Inputs

Con: * Lack of wiring diagram resources available to connect existing
(factory installed) rear camera functions.
* Intermittent problem not restoring GPS functions after NAV In-
Motion. On rare occasions you must manually return to
normal function.
* Factory “in-motion” warning from top of screen while in video
mode.

Bottom-line: I’m very happy with my purchase and the performance of the GMX-550. I am considering installing turn-signal cameras on the side mirrors to compensate for blind spots. I also used the back-up function and installed a mini camera above my trailer hitch and can very quickly land the hitch and ball at any angle with extreme accuracy. I look forward to additional firmware upgrades.

Still getting to know it

This is the coolest mod for a vehicle. Not much in the way of instructions but fairly simple to install after determining how the various panels on my escalade come off.
I made some mistakes such as installing my side view cameras so I have to look at the bottom of my mirrors each time. In hindsight I shouldn't have bought reverse image cameras for the side mirrors. It looks like you are looking at the opposite side of the truck. I am still trying to get used to this. Some problems with the ipod menus but this unit is still ultra cool!

lockpick for my Suburban

I purchased the lock pick and it was very easy to install. It does everything that the sellers say it does. I did notice that the gps doesn't work when its activated. so that's the main thing I dislike about it.

Good product

I would recommend this to others who are wanting to add a camera input or wanting to bypass nav input while driving or bypass DVD input while driving. I would not recommend this to someone who is strictly looking to add iPod functionality to your system. The iPod functionality is sketchy at best when using steering wheel controls.
Pros: Price for options added, Ease of install
Cons: iPod functionality from steering controls works when it wants to, I can start my truck not touch the iPod and steering controls may work press play turn off truck start again steering controls will not work. Next time I start they may or may not work if it works from the beginning it will work 100% until the next time I try.

GMX 550 is average at best

I have a 2007 Yukon Denali and I have had nothing but problems with mine. I have had it installed since 3/2009. Coastaletech customer service is horrible!! Carlos, the tech support guy is great though. I ordered mine from a 3rd party and Crappy Coastaltech will not warranty it even though it is their product. The 3rd party said I could send it back and they could test it out? How in the hell are you gonna test it out?

My issues are Navigation is flaky, doesn't work consistently. Lately the navigation doesn't know where I am. Sometimes the Override option in the GMX switches from 3 to 2 and screws it all up. My latest issue is when I connect my iPhone 4s it will play the music but won't display anything on the screen. My other bug is now DVDs won't play on the front screen. I have just about had it with this product.

My firmware version is 1.4 but the site says 1.3. When you check the update link, it takes you to a dead page.

This will be my very last purchase from the USELESS company who only cares with selling and not supporting their product. I had an old GMX 320, and I upgraded to the GMX550. I had less problems with that although it had less functionality.

Sonic Electronix offered an RMA to send it back to Sonic and see if they can replicate the problem. I highly doubt they have a 2007 Denali sitting around to test my issues out on, so I passed on it. Now I am stuck with $320 worth of useless junk. I feel like I am using DOS when using my 550, so clunky and not smooth at all.

I am not frustrated as much with Sonic Electronix as I am with Coastaletech. They (Coastaletech) said since I didn't buy it directly from them, they don't honor the 1 year warranty. Coastaletech is absolute garbage. Stay away if you want a product that works 100% of the time, but if you want a product that works off and on feel free to waste your $$ on the GMX550. Hopefully SonicElectronix will stop carrying this product!!

Excellent Product Great Value

Unit was easy to install. Small and compact so it easily fit behind the navigation unit. Worked as advertised and best of all it did not interfere with normal system operations.

Lock Pick in my 07 Escalade

WOW, what a great device. Easy connections. Takes some time to get used to the controls, but well written in the manual.

A few more tweaks would make this a nicer unit....

Has some kind of internal circuit breaker that trips out for no reason. It stop at the store and turn off the truck with everything working fine. Get back in and nothing works! black screen on the radio, no power, no sound. I've had to pull the battery cable to reset it.
But i still have it installed and don't want to be without my iPhone in the truck. It is still the best option out there, it just needs a few tweaks to make it better.
