Question: Garmin dezl truck sat nav 770LM. Power cable, please could you advise of the correct cable and price?
Answer: There are three vehicle power cables that you could buy from:
1. Garmin dezl 770 Vehicle Power Cable - (vehicle power cable only - NO traffic information)
3. Garmin dezl 770 GTM 36 FM Traffic Receiver - (vehicle power cable with FM analogue traffic services)
All three vehicle power cables can be viewed and purchased on the Garmin dezl 770 Accessory webpage.
Question: I am after a traffic receiver cable for my truck sat nav, it is a Garmin dezl 770LM.
The label on the sat nav says it is simply an LM model, but when you search the S/N it shows up as a LMT-D however it doesn't have any traffic built in, so I am a bit lost.
Do you have anything that will work with this model?
Answer: The cable to purchase is the Garmin GTM 36 FM Traffic Receiver: this cable uses the FM radio frequency to receive live traffic updates.
You can also view all compatible accessories for your Garmin dezl 770LMT-D here.
Question: I have a Garmin dezi 770 lmt-d truck navigator. Do you do a hard case to fit this please? I have bought one from a company saying it will fit, but it is about half a inch to small. Also can you give me internal measurements please?
Answer: We do not sell a hard carrying case for the Garmin dezi 770 LMT-D truck. To our knowledge Garmin do not make one that is compatible with the 7-inch dezi 770. We only sell genuine Garmin accessories.

Question: I have a garmin 770lmt satnav. Can you please tell me the difference in my satnav and snooper bus and coach satnav. I'm a tour coach driver.
Answer: I'm presuming you have the Garmin dezl 770LMT designed for trucks? As there is also a nuvi 770LMT designed for cars.
The main and only real difference is that the Snooper bus and coach models include POI (Point Of Interest) information specific to a coach/bus driver. The Garmin dezl and Snooper Truckmate model include a POI (Point Of Interest) database for truck drivers. View the Snooper bus and coach models.
Question: I have the just bought the Gamin dezl 770 LMT-D and am unsure which voltage input it takes. My truck only has 24 volt socket so, do I need to buy a dropper to bring it down to 12 volts? Also I can't seem to find a case to fit it anywhere.
Answer: With regards the vehicle power cable, I would recommend that you look closely at the cable that was supplied with your purchase. The cable we sell and which comes with Gamin dezl 770LMT-D that we sell says "Input 10-24V".
As for a carrying case, this can be purchased online here.

Attached to this are two small suction cups for, I'd imagine, windscreen mounting the cable. So what exactly is this mysterious cable?
Answer: The cable is used for boasting the traffic reception when connected to the GTM 36 traffic receives.
The cable is called the Garmin GTM 36 External Antenna Cable and is pictured right.
