GTM 11 Experts. HELP

[cantgetlost]

Fitted up GTM 11 to the Nuvi 350 yesterday. And had solid red light all the way from GPSW down M3 and on M25
Called Garmin today helpful chap said I had it connected OK and try changing aerials over.
Had no Joy and then 10 minutes later went to the car and had green lights and traffic info.
Headed for M3 and M25 this afternoon straight into heavy traffic and just have solid red light again ( no connection) have tried both aerials again and even stood on top of the car on a hill with no effect.
Does anyone know of FM problems in the area with the service or do I have a duff unit?

Ok.
took unit back as it seemed not to work GPSW agreed and changed the unit, plugged it in, the car park and it updated TMC data etc and led changed and hey presto I had traffic info .
Set a route for deepest darkest Slough trading estate with unit showing problem on A4 to Slough well I was well impressed until the red LED came on approaching Slough.
No doubt all my loyal readers have guessed, it is still on red and was all the way home.
I can't believe the M25 and all roads were clear and I'm baffled by the unit. IS IT ME ?
Or am I missing something
Be careful how you answer
