I recently purchased a used GMX-322 Lockpick off of Ebay for my factory Nav Radio in my 2007 Silverado. I installed it properly and set the dip switched properly. I press the mute 4x indrive and the DVD shows, then as I begin to drive the DVD movie gets blocked again around 8 mph!!!.

I did some research and seen others with similar problems with the Lockpick and the Nav map disk 4.0c version.

So I purchased a new 5.0c Nav Map disk off Ebay for another 99.00.

Put in new disk and press mute 4x in drive, DVD movie shows on screen...begin driving slow....all fine.......go faster than 8 mph and the blue driving restriction screen pops on!!

Tried calling Coastal but they never answer and never email me back.

What to do???? Ready to give up.

 

That's a common complaint w/ those folks.

 

what's the newest lockpick version?

the newest map data is 6.0c

 

I called them and emailed them questions before and they got back to me same day...maybe try them again, I have not heard of that issue. I mean that is the exact thing the lockpic is supposed to NOT do...?
hopefully you didnt buy a faulty lockpic on Ebay

 

I finally got ahold of Coastal and they helped me figure it out.

I had the dip switches set wrong for my application.

Works good now.

 

darn you got us all worried here man, but I'm glad it worked out ok for you!!!

 

who's the dip switch now?

just messing

glad it works, and they got back to you, makes me slightly more likely to buy one...

 

Yeah it works, but im still not very impressed by the whole factory Navigation and lockpick setup.
Like has been said before......a $200 tomtom or garmin does a much better job.
But I like the clean factoy look of the in dash OEM Nav radio, so I guess it will do.

 

I am in the same boat - the clean built in look is worth a lot to me. personally I think it works just fine, don't really understand what a $200 Garmin would do better? other than the dumb yearly updates they try to sell for $200

1 thing I really hate is how you can't really scroll or move on the screen other than touching it to re-center over and over. or am I missing something?
the navigation on my Acura has a little joystick thing that makes it much easier to move around on the map.

 

You can scroll by touching the screen and dragging and holding it 'til it gets to where you want it.
