    I have the same problem. I've had this thing for almost a yaer now and the speaker is screwed up. You can still hear it but it sounds terrible, like the speaker is blown. I want to know what it will cost me to fix it and how long would it take.

I called cobra support(777-889-3087) and it was around $6 plus shipping for a replacement speaker.
the correct phone number for cobra support is 773-889-3087 and can be found on their website.
Cobra was very courtious and I also got my replacement speaker for my XRS-9500.!

I contacted Cobra via internet site and ordered the speaker. However, it has been on order for over 6 weeks and still not here. I would have figured this would be a relatively high failure item and would be stocked. Thanks for the response. ohmhead

Cant find a replacement fuse for the power cord


the fuse is located in the cigarette lighter plug, at the end you will see a silver cap and then the disk that goes over the top of it, that will turn and then you will have the front open to replace the glass fuse that is in it... to find the fuse size, after the fuse is out look at the silver ends it will have the size stamped on it... it might be a 40 amp fuse. or 20 amp. just look at the silver sides on the fuse you will find that there... hope this helps you out

Cobra xrs757 X Band


The x-band is the considered a "trash band". It picks up things like automatic doors at supermarkets and such. About every radar detector made has an X band for non-police radar. There is no way to turn this band off on the XRS-757.

Holding down the dim button for 2 seconds turns the V alert on/off
Holding down the city button for 2 seconds turns the Spectra on/off
Holding both city and dim together for 2 seconds turns K and Ku band on/off.

I need a manual for a cobra xrs 757 for a radar detector any idea where i can find one


The Cobra XRS-757 is the same as the Cobra XRS-9330. The difference in model number is due to the 757 being sold at Wal-Mart stores.

There are 2 options for power plugs that can be purchased from Cobra for the 757. The straight 12V power cord is listed under item number: 420-030-N-001 and the coiled 12V power cord is listed under item number: 420-026-N-001. Both can be purchased from Cobra by calling their order line at: 773-889-3087 or visiting www.cobra.com

Radar detector speaker busted


The best way is to call up cobra or ask them a question through their site.

http://www.cobra.com/index.cfm?fuseaction=support.ask

This will link you to the ask page. Just ask if they will sell you a replacement speaker for the radar detector xrs 747. I just ordered one for a friend and it was $4.32 and $2.50 for shipping.

Cobra 757 codes


X stands for wide band radars(easy to detect,lots of false alarms)
K/Ka stands for pulse band radars(similar signal has auto doors)
W,L stands for laser detection (very little false signals)
Ku stands for signal most used on speed cameras
V stands for radar detectors detector
Have in mind that you can only lower your speed 20-30 km/h in city zones, and up to 50 km/h on highway.This depends on car,brakes and You.
