Problems with Garmin TMC unit

Please can anybody put some light on this problem.

I have a Kenwood KNA-G50 stand alone hide away Sat-Nav unit which is a
Garmin GVN 52 with GTM 10 FM Traffic (TMC) receiver fitted to a Kenwood
KVT-827DVD multimedia player.

This was fitted about a year ago on a 06 year Kia Sorento UK model
professionally with no problems until recently the above Sat-Nav unit packed
up at Heathrow airport after picking up family... The Sat-Nav unit was
replaced free of charge as I believe the hard disk failed.

Since the new Sat-Nav has been installed the TMC unit (GTM10) does not
display any traffic situations, just says 'None Fond' on the screen although
it is set to search automatically with a strong signal. Situation is
unchanged if set to Manuel.

The vehicle was returned to where it was fitted after 2 weeks with the
traffic TMC unit indicating 'None Found' and after checking for loose wires
etc, the TMC unit was replaced with another new traffic TMC unit which
immediately began to work by picking up traffic reports. This lasted about 1
hour before all of a sudden the new TMC unit went the same way as the
previous unit displaying 'None Found'.

I have also had installed recently a TV tuner that sits under the drivers
seat with the Sat-Nav and TMC unit.

Kenwood was contacted by the installers with this problem and they have no
insight as to what is causing this problem.

Any suggestions would be welcome.

Regards

Steve

First of all make sure it is not the TV thing. Unplug, better
uninstall it, and see.

Then, I would check if the GPS unit is faulty and "grills" the TMC
receiver to death over time.

Try removing all power to the TV tuner.
