I just bought a 07 LTZ. I am looking for a unlock unit to watch DVDs up front and use GPS while driving. Has anyone purchased one that they recommend? I am thinking about the GMX-322 from Coastal e Tech. Thanks

Gm has a bulletin as far as using this kind of hardware. Document ID 2100319. Some people have not had any problems with their coastal tech pieces, but I have seen vehilces come into our dealership with data comunication issues.
Just letting you know to remove your coastaltech unit before you go into a GM service dept, if you have any problems.

google 'lock pick' i think? not a cheap solution, but i guess it does that

can you voice in addresses when in motion? the Jeep Grand lets you do that... but not type them in...

I did install the GMX322 in a 2007 Suburban and no problems so far. Works as intended.

I am using a Bluetooth Parrot set and the Lockpick iPOD interface, in conjunction with the 322.
