Need Repair/Exact Replacement for Radio Shack Car Alarm

Dear Experts:
The Brain Box for this inexpensive car alam needs to be replaced or repaired(I would hate to change all of the wirining in the car, and I do not want any fancy features - i.e. push button activators for key ring). The unit is called Mobile Alert, keyless electronic vehicle alarm system, with motion sensor, and the catalogue number is 49-759. Radio Shack has been of no help. If I could find an exact replacement, then I could simply plug it back in and the system would work again. If I could find someone to repair this unit, that would be fine too. The unit was made in Hong Kong for Radio Shack, so if I could find the manufacturer, perhaps they could help.

My Cobra radar detector failed when the audio speaker failed. Can I fix it?

you can take a speaker out of a used cordless phone. I did that and replace the speaker and works great.

The tip is missing on my power cord Whistler XCS also has rechargeable batteries but seems like it won't work without power cord. So is the cord easy to replace? Does that mean the detector is...

You can buy cigarette lighter power supplies at radio shack, they sell a wide variety of voltages and tips to fit almost any device (radar detector) you may have.
The 4 things you need to know (which you may be able to find off of the broken power cord
  • voltage, your car is ~12VDC (volts DC) but your device may need something lower
  • amperage, your device has a certain power draw, as long as your new plug has the same or higher you are good (ie: your device may say 500mA, you can use a 1A power plug (1A = 1000mA)
  • tip size, these vary from device to device, best thing is to bring it into Radio Shack with you and size it up there
  • polarity, what is positive and what is negative (on the tip), this may also be found on the old power plug or manual, or sometimes on the device itself)
I hope this helps,

I need the pin connector where the powercord plugs into the unit.

You might be able to find this at your local radio shack. Take the detector with you - the staff is usually pretty helpful. Opening the unit up may be tricky.

I no longer get a bright display. The display stays on dim even when I switch to bright. I cannot see the screen at all during the day. I have a Cobra XRS 9930 that has developed a very dim display....

I had the same problem. I also live in Florida and I guess the display overheated in my hot car after time. I eventually bought a new one but it did the same thing.

Does Best Buy install car alarms by viper

Best buy will install viper car alarms, but I would strongly advise against getting any work performed by their techs. I had one installed on my truck and aside from not working properly, the cruise control, heater control unit, power windows, sunroof, and gauge cluster have stopped working. All that on top of intermittent stalling on the interstate. So far the repair estimate from a Toyota dealer is nearing $2000.
While this may be an isolated incident, Best buy will certainly not get any more of my money.
