Help – I think a Visseo MB3 broke my car

[w203owner]

Hello

I would be grateful if someone could suggest possible causes for UHI Power issue.

My UK spec 2005 W203 C220 CDI Estate was factory fitted with the UHI Telephone prewiring option, an Audio 20 radio and a Nokia 6230i cradle adapter in the armrest.

Recently I unwittingly connected a faulty brand new Viseeo MB3 to my UHI port. The system worked perfectly for about 10 minutes before I lost power to the Viseeo.

I have a replacement Visseo MB3 but still do not get any power to it.

Surprised I still had the Nokia, I tried it in the armrest but still no power and “No Phone” on the dash.

All the fuses seem to have continuity.

I have found the control unit in the boot. Are there any PINs I could check for supply voltages?

Many thanks

I think it will be the telephone module that has gone down by the sounds of things

Hey Television,

Thanks for the prompt reply.

The telphone unit. Is that the control unit behind the spare tyre in the boot?
