I am sure most of you at one point in time have purchased a used XM module from a junkyard. Or have swapped units from one vehicle to another, only to encounter one of the above error messages.
A trip to the dealer has proven unsuccessful and programming the used module's VIN number into the BCM is not
the correct approach to take. Yes, the Tech 2 is useless in this aspect.
This past Wednesday, I went to the dealership to hopefully get the module reprogrammed. My dealer was very willing to reprogram the module (~$45 fee) but was unable to. A call to GM returned that once the module is programmed, it cannot be reprogrammed. While this is true, it does not mean that the module's EEPROM cannot be cleared, thus paving the way for a VIN relearn.
After hearing the above from my dealer, I stuck around and attempted to get in touch with the "Master Corvette Mechanic
" named Joe Malo. The guy cannot even be reached and a guy I spoke with over the phone did not
want to hear any of it. Apparently, Joe Malo was "too busy with what he's doing at the moment." All I wanted was for the two dealerships to speak to each other. Oh well.
So, I got home and Google'd my ass off again trying to find some information/a solution. I ended up finding a Chevy Avalanche forum
where user SpottyJ
linked to another forum about a possible solution. It was a user named 98Blackss
who eventually found a solution
. He was able to get a radio service center to reflash the unit. So a few PMs later and I was in touch with the service center and overnighted my unit. Like 98Blackss
, I was warned by the service center that this was not a guaranteed fix. I agreed and understood any limitations.
They received the unit Thursday. I called Friday and paid the fee plus overnight Saturday delivery. After receiving my unit today and testing it out, the "XM Locked" message on the NAV screen is gone!
I spoke with a lead engineer named "Kevin" on Thursday and he said they would have no problem with "fixing" these units.
The company's name is Instrument Sales and Service, Inc.
and they are located in Kent, WA
. Their telephone number is 1 (800) 666-5469
and their website is http://www.instrumentsales.com
You would obviously have to get in contact with them before sending in your unit.
The test bench fee is $35
. This service reflashes the module and then tests on the Alpha, which is apparently setup to make sure the module is communicating with all the XM satellites. This fee may or may not change depending on the demand. So it would probably be best to call and inquire.
Overall, I am very satisfied with their service and I would definitely do business with them again. The company was very professional, very knowledgeable, and very helpful with this matter. I would highly recommend them to anyone (not that there's another known choice out there, lol).
A picture of my NAV screen after turning on the vehicle:
I do not have an all-in-one (OnStar, GPS, and XM) antenna yet so I cannot test out the previews. My antenna is simply OnStar and GPS. The good thing is that "XM Locked" is gone!
The packaging that I received the unit in is very
professional! Their overnight shipping price was also very
for standard overnight, $20
for overnight Saturday delivery). Considering that I sent the module wrapped in bubble wrap and squeezed into a USPS overnight envelope.
Start making calls Monday and good luck!
