Webasto Telestart Kit

[Lamby]

Hi Everyone, Okay... I am ready for a hiding to nothing from everyone because this is quite a posted topic. But, I need some clarity and a lot of the threads I have read run off on some bizarre tangent about Squirrels or the best way to make homebrew.

So. If I can get some answers I will do a write up and post photos and send my thanks in return (maybe even a photo of a London Squirrel!). What I guess everyone needs to know from the start is that I have a Webasto Heater in my 2004 (face lift) X5 E53 and it has the water pump thing etc... I do not have Nav/TV installed I have BMW CD/OBC instead so can't comment on the Aux Vent / Heat debate as I can't see it having no Nav/TV.

Questions are

1. Do I need to have anything coded, if I am just going to ADD the Telestart Remote Kit? i.e. I am just going to do some electrical wiring and install the kit?

2. Found a couple of links,
Simple one way radio switch from Maplin (Radioshack to our US brothers) Via the Pin 1 out of the webasto heater by the engine and run powers,fuse, control box accordingly. Get a Telestart kit, Modify Pin Plug to fit in Rear Boot (Trunk), install antenna and then that is it, plug and play!

1. Parking heater remote start- Enabling Parking heater remote start- Enabling
2. Adding telestart t91 Adding telestart t91

So, I would like some advice on, if I don't need to code, the easier job seems to be option 2, I have a budget of £150 (Post-Brexit its about $150) so it seems I can afford a Telestarter Kit and do option 2?

Thank you and happy Friday to you all.
Lamby.
